Sistem otomasi ataupun kontroler tidak akan lepas dengan apa yang disebut 'sensor'. Karena suatu sistem pengendali secara garis besar mempunyai prosedur dan rangkaian proses yang saling berkaitan. Bermula dari proses perubahan yang ditangkap dan diolah oleh pengolah sinyal/data yang kemudian diteruskan sebagai keluaran dari olah data dalam bentuk kondisi pengendalian. Semua proses tersebut juga akan di adopsi pada dunia robotika dan bahkan rangkaian proses tersebutlah yang menjadi suatu proses rutin/inti dalam bagian bagian robot yang dapat digambarkan sebagai aliran darah suatu robot.
Apa itu Transduser ?
Transduser adalah alat yang mengubah suatu energi dari satu bentuk ke bentuk lain, yang merupakan elemen penting dalam sistem pengendali. Secara umum transduser dibedakan atas dua prinsip kerja yaitu:
pertama, Transduser Input dapat dikatakan bahwa transduser ini akan mengubah energi non-listrik menjadi energi listrik.
Kedua, Transduser Output adalah kebalikannya, mengubah energi listrik ke bentuk energi non-listrik.
Bagaimana dengan Sensor ?Sensor adalah alat untuk mendeteksi / mengukur sesuatu yang digunakan untuk mengubah variasi mekanis, magnetis, panas, sinar dan kimia menjadi tegangan dan arus listrik. Sensor itu sendiri terdiri dari transduser dengan atau tanpa penguat/pengolah sinyal yang terbentuk dalam satu sistem pengindera. Dalam lingkungan sistem pengendali dan robotika, sensor memberikan kesamaan yang menyerupai mata, pendengaran, hidung, lidah yang kemudian akan diolah oleh kontroller sebagai otaknya.Macam-macam Sensor ?Sensor Kedekatan (Proximity), yaitu sensor atau saklar yang dapat mendeteksi adanya target (jenis logam) dengan tanpa adanya kontak fisik. Sensor jenis ini biasanya tediri dari alat elektronis solid-state yang terbungkus rapat untuk melindunginya dari pengaruh getaran, cairan, kimiawi, dan korosif yang berlebihan. Sensor ini dapat diaplikasikan pada kondisi penginderaan pada objek yang dianggap terlalu kecil/lunak untuk menggerakkan suatu mekanis saklar. Prinsip kerjanya adalah dengan memperhatikan perubahan amplitudo suatu lingkungan medan frekuensi tinggi.Sensor Magnet - juga disebut relai buluh, adalah alat yang akan terpengaruh medan magnet dan akan memberikan perubahan kondisi pada keluaran. Seperti layaknya saklar dua kondisi (on/off) yang digerakkan oleh adanya medan magnet di sekitarnya. Biasanya sensor ini dikemas dalam bentuk kemasan yang hampa dan bebas dari debu, kelembapan, asap ataupun uap.Sensor Sinar - terdiri dari 3 kategori. Fotovoltaic atau sel solar adalah alat sensor sinar yang mengubah energi sinar langsung menjadi energi listrik, dengan adanya penyinaran cahaya akan menyebabkan pergerakan elektron dan menghasilkan tegangan. Demikian pula dengan Fotokonduktif (fotoresistif) yang akan memberikan perubahan tahanan (resistansi) pada sel-selnya, semakin tinggin intensitas cahaya yang terima, maka akan semakin kecil pula nilai tahanannya. Sedangkan Fotolistrik adalah sensor yang berprinsip kerja berdasarkan pantulan karena perubahan posisi/jarak suatu sumber sinar (inframerah atau laser) ataupun target pemantulnya, yang terdiri dari pasangan sumber cahaya dan penerima.Sensor Efek-Hall - dirancang untuk merasakan adanya objek magnetis dengan perubahan posisinya. Perubahan medan magnet yang terus menerus menyebabkan timbulnya pulsa yang kemudian dapat ditentukan frekuensinya, sensor jenis ini biasa digunakan sebagai pengukur kecepatan.Sensor Ultrasonik - bekerja berdasarkan prinsip pantulan gelombang suara, dimana sensor ini menghasilkan gelombang suara yang kemudian menangkapnya kembali dengan perbedaan waktu sebagai dasar penginderaannya. Perbedaan waktu antara gelombang suara dipancarkan dengan ditangkapnya kembali gelombang suara tersebut adalah berbanding lurus dengan jarak atau tinggi objek yang memantulkannya. Jenis objek yang dapat diindera diantaranya adalah: objek padat, cair, butiran maupun tekstil.Sensor Tekanan - sensor ini memiliki transduser yang mengukur ketegangan kawat, dimana mengubah tegangan mekanis menjadi sinyal listrik. Dasar penginderaannya pada perubahan tahanan pengantar (transduser) yang berubah akibat perubahan panjang dan luas penampangnya.Sensor Suhu- ada 4 jenis utama sensor suhu yang biasa digunakan; thermocouple (T/C), resistance temperature detector (RTD), termistor dan IC sensor. Thermocouple pada pokoknya terdiri dari sepasang transduser panas dan dingin yang disambungkan/dilebur bersama, perbedaan yang timbul antara sambungan tersebut dengan sambungan referensi yang berfungsi sebagai pembanding.Resistance Temperature Detector (RTD) didasari pada tahanan listrik dari logam yang bervariasi sebanding dengan suhu. Kesebandingan variasi ini adalah presisi dengan tingkat konsisten/kestabilan yang tinggi pada pendeteksian tahanan. Platina adalah bahan yang sering digunakan karena memiliki tahanan suhu, kelinearan, stabilitas dan reproduksibilitas. Termistor adalah resistor yang peka terhadap panas yang biasanya mempunyai koefisien suhu negatif, karena saat suhu meningkat maka tahanan menurun atau sebaliknya. Jenis ini sangat peka dengan o perubahan tahan 5% per C sehingga mampu mendeteksi perubahan suhu yang kecil. IC Sensor adalah sensor suhu dengan rangkaian terpadu yang menggunakan chipsilikon untuk kelemahan penginderanya. Mempunyai konfigurasi output tegangan dan arus yang sangat linear. Sensor Kecepatan/RPM - proses penginderaan merupakan proses kebalikan dari suatu motor, dimana suatu poros/object yang berputar pada suatui generator akan menghasilkan suatu tegangan yang sebanding dengan kecepatan putaran object. Kecepatan putar sering pula diukur dengan menggunakan sensor yang mengindera pulsa magnetis (induksi) yang timbul saat medan magnetis terjadi.Sensor Penyandi (Encoder) digunakan untuk mengubah gerakan linear atau putaran menjadi sinyal digital, dimana sensor putaran memonitor gerakan putar dari suatu alat. Sensor ini biasanya terdiri dari 2 lapis jenis penyandi, yaitu; Pertama, Penyandi rotari tambahan (yang mentransmisikan jumlah tertentu dari pulsa untuk masing-masing putaran) yang akan membangkitkan gelombang kotak pada objek yang diputar. Kedua, Penyandi absolut (yang memperlengkapi kode binary tertentu untuk masing-masing posisi sudut) mempunyai cara kerja sang sama dengan perkecualian, lebih banyak atau lebih rapat pulsa gelombang kotak yang dihasilkan sehingga membentuk suatu pengkodean dalam susunan tertentu.Apa itu Actuator (penggerak) ? Penggerak, dalam pengertian listrik adalah setiap alat yang mengubah sinyal listrik menjadi gerakan mekanis. Biasa digunakan sebagai proses lanjutan dari keluaran suatu proses olah data yang dihasilkan oleh suatu sensor atau kontroler. Terdiri dari 3 jenis pokok : Relaiadalah alat yang dioperasikan dengan listrik dan secara mekanis mengontrol penghubungan rangkaian listrik, bermanfaat untuk kontrol jarak jauh dan untuk pengontrolan alat tegangan dan arus tinggi dengan sinyal kontrol tegangan dan arus rendah. Bekerja berdasarkan pembentukan elektromagnet yang menggerakkan elektromekanis penghubung dari dua atau lebih titik penghubung (konektor) rangkaian sehingga dapat menghasilkan kondisi kontak ON atau kontak OFF atau kombinasi dari keduanya. Selenoidadalah alat yang digunakan untuk mengubah sinyal listrik atau arus listrik menjadi gerakan mekanis linear. Terbentuk dari kumparan dengan inti besi yang dapat bergerak, besarnya gaya tarikan atau dorongan yang dihasilkan adalah ditentukan dengan jumlah lilitan kumparan tembaga dan besar arus yang mengalir melalui kumparan. Stepper adalah alat yang mengubah pulsa listrik yang diberikan menjadi gerakan rotor discret (berlainan) yang disebut step (langkah). Satu putaran motor memerlukan 360 derajat dengan jumlah langkah yang tertentu perderajatnya. Ukuran kerja dari stepper biasanya diberikan dalam jumlah langkah per-putaran per-detik. Motor stepper mempunyai kecepatan dan torsi yang rendah namun memiliki kontrol gerakan posisi yang cermat, hal ini dikarenakan memiliki beberapa segment kutub kumparan. Motor DC adalah alat yang mengubah pulsa listrik menjadi gerak, mempunyai prinsip dasar yang sama dengan motor stepper namun gerakannya bersifat kontinyu atau berkelanjutan. Motor DC dibagi menjadi 2 jenis yaitu ; Motor DC dengan sikat (mekanis komutasi), yaitu motor yang memiliki sikat karbon berfungsi sebagai pengubah arus pada kumparan sedemikian rupa sehingga arah tenaga putaran motor akan selalu sama. Motor DC tanpa sikat , menggunakan semi konduktor untuk merubah maupun membalik arus sehingga layaknya pulsa yang menggerakkan motor tersebut. Biasa digunakan pada sistem servo, karena mempunyai efisiensi tinggi, umur pemakaian lama, tingkat kebisingan suara listrik rendah, karena putarannya halus seperti stepper namun putarannya terusmenerus tanpa adanya step. + Rano (Sumber: Buku Elektronik Industri, Frank D.

Tips n trik pengInstallan PC :

Sebelum melakukan install ulang pada sebuah PC.
Perlu diperhatikan driver dari hardware yang dimiliki.
Walaupun hardware tersebut dapat bekerja dengan baik pada OS sebelumnya.
Pada saat harddisk selesai diformat semua data baik yang baik pun yg kurang akan habis dibuang (namanya aza di format).
Persiapkan CD install (driver n program).
Bgm kalo cd driver ngga da lagi alias hilang alias rusak alias ngga bisa digunakan lagi. Tukar motherboard. Jangan dulu. Driver yang telah terinstall dapat di ambil lagi menggunakan sejenis program Aida32 -> phitok gunakan yg ini.

habis itu selurh driver di burning ke CD atw di simpan di dalam flash disk atw diskette kalo muat. When it's done. U can start to install ur PC safely.

Tips n Trik 4 ur symbian60

* How to reset the operator logo :

1) go to the following dir :

c:\system\apps\phone\oplogo

1) delete any file in this directory

3) restart the phone

* to make a screenshot on a Nokia 3650, 6600 :

1) use the pencil key + '0'
2) the screenshot is saved in C:\NOKIA\IMAGES\FE_img\

* to make a screenshot on a SX1 :

1) use the shift key + '0'
2) the screenshot is saved in C:\NOKIA\IMAGES\FE_img\

* remember, there are some shortcuts :

: copy
: show path (scroll with joystick left/right)
: PageUp
: cut
: *not yet used*
: top of the list
: paste
: *not yet used*
: PageDown
: Mark / Unmark a file
: go to root
: file properties
: delete a file

* 'send command' fails new firmware :

with some new firmware, some users have reported that the 'send command' (thru bluetooth, IR, ...) fails; it's due to a 'copyrigth protection' introduced in the new OS (!!!!), this happens only with some kind of files (eg: .SIS), in such case, simply rename the file (eg: wtih .SIS_ ) before trying to send them.

* problems during installation (Nk6600, N70, ... ) :

If, after the installation, you don't see the FExplorer icon in the main panel of the phone, the .sis file is maybe corrupted, in this case, re-download it from my site and try the installation once more, if the problem persists, try to remove (desinstall) any previous version (with the application manager) before installing the last version (11/11/2005).

* problems during installation (Nk6630, 6680, ... ) :

If you get some messages during the installation (ex: 'Installation security error. Unable to install', ..); go to the application manager for software installation, and change the 'Application access' to 'on' (instead of 'Signed only').

* problems when starting (Nk7610, ... ) :

If you get directly some messages when FExplorer starts (ex: 'closed application : fexplorer'), try to de-install any previous version instead of installing the last version as 'update'.

* running exe files :

With version 1.13, I have introduced, in the directory of FExplorer a console exe file : EXETEST.EXE (you can run it), the purpose is only to test if FExplorer can run EXE files on your phone.

* the settings file :

With version 1.13, I have introduced, a new kind to save the settings but this file can grow (don't know why...), this file is located in the directory of FExplorer (\system\apps\FExplorer), the name is FEgen.ini, if you find this file too big, simply, delete it, it will be re-generated with the current settings.

* restoring the last path in views :

After leaving the 'about box', 'settings' or the 'editor' view, if FExplorer return to the root directory, check that the 'save last path' in the settings is 'ON', not only this settings is used when leaving FExplorer but i's also used in all the differents 'views' (06/03/2005).

* how to switch between the text/hex viewer :

Simply, go to the settings and choose the viewer type : text or hex (06/05/2005).

HISTORY....!!!

FExplorer V1.15 (November 5th, 2005)

  • in a search, if a directory is found, the right key enters into this folder.
  • the full path of the files is displayed while browsing the inbox, process and tasks.
  • A check (with a message) is now performed before copying or moving files to ensure there is free space enough on the destination drive.
  • in the 'tools menu', added a function to directly call the bluetooth manager.
  • added a progress dialog with the name of the file being copied.
  • in the hex viewer, the keys '3' and '9' can be used as page-up, page-down.
  • in the hex viewer, when in full screen mode, the file is displayed on 8 bytes, the ascii characters are displayed at the top, line per line.



  • in the hex viewer, with small files, corrected a bug to avoid FE to panic and exit when going down 'too deeply' in the text.
  • added a function in the 'edit' menu to invert the selection of the current directory - marked files and dir become un-marked and un-marked become marked.
  • it's now possible to mark folders (like the files) and copy/cut/paste them with the files.
  • added the latest phones in the phone type list (3230,6680,6681,6682,N70,N90).
  • added, in the 'tools' menu, an option to dump (into a log file placed in the root) a list of *all* the installed applications with their UID and their path; this file can then be sended to the pc via bluetooth, infrared; the result is something like this (06/29/2005) :



  • when displaying the full path in the 'small scrolling windows (key : [2])', the [1] key copies the full path and filename into the clipboard to be used in the notepad, ....
  • after a 'compress memory', the new -free memory- value is displayed in the navigation pane (ie: the screen is refreshed).
  • fixed the bug to avoid to use 2 times the 'NO' key on exit.
  • the attributes of a file can now be modified.

  • it's now possible to save the screenshots either in the phone memory or in the MMC.



  • like the processes, the currently running tasks can be displayed, kill, ...

Version 1.14b

  • this version was a beta with an expiration date.

Current Version 1.13

  • added the lastest phones in the phone type list.
  • suppress 'send by infrared' on N-Gage QD.
  • the files taken from the screenshot are now
    numbered 001, 002, ....
  • Added a 'goto path' in the 'file find' panel.
  • Access to files contained in the 'inbox' directly
    from the root.
  • Multiple files copy/paste/cut/delete is now available (shortcut [0] in used in this case).
  • A scrolling window can be display to show the whole path and filename (shortcut [2] is used, scroll is done with joystick left/right).
  • You can now display the content of a file either
    with the build-in text viewer or in hexadecimal.

Version 1.12b

  • this version was a beta with an expiration date.

Version 1.11

  • the screen shot is fixed for the Nokia 6600.
  • the last search is saved for the next session.
  • more infos have been added in the 'phone/info' menu.
  • a new sub-menu has been added in the 'tools' menu to compress the memory (with the available memory
    before and after the compression).
  • shorcut '6' has been added to go to the top of the list

Version 1.10

  • a message is displayed when a screenshot is saved.
  • added the time in the properties of the files and the date and time in the properties of a directory.
  • the number of the last screenshot is saved and continue with the next version (to avoid overwrtting).
  • the icons associated with the files (if so) are now displayed in the list.
  • you can now turn the infrared ON from the Tools menu.
  • I have improved the quality factor of the images captured with the screenshot, the image is now captured at 176 x 208 instead of 176 x 188.
  • it's now possible to run the .EXE files (not only .APP, ex: to run console applications).
  • in full screen mode, the size (free/total) of the drives is displayed at the top of the screen if activated.
  • before exiting FE, the last directory is saved for the next use if selected in the settings.
  • the network info box displays also the area id and the cell id.
  • when exiting the editor-viewer, the previous path is kept.
  • it's now possible to delete read only files after a confirmation message.
  • some shortcuts have been added :
    : copy
    : PageUp
    : cut
    : paste
    : PageDown
    : go to root
    : file properties

Version 1.08
  • added a menu : network information.
  • in the 'file menu', it's now possible to set a picture as an operator logo (last point of the menu); jpg and gif are resized, bmp none.
  • a 'settings menu' has been added that allows to configure FExlp. (the settings are saved); you can set up the color in lists, the display of the full path in full screen mode the full screen mode.
  • a confirmation dialog is showed before quitting the pgm.
  • the restart function has a confirmation message
  • it's possible to edit (in fact view) the files (like ini...).
  • the size of the files are displayed on each line and the font is smaller to display more character.

Version 1.07 :
  • the info-boxes of the drives and files properties have been enhanced, also added the hidden,archive,r/o and system attributes of the files and the 3 UID's.
  • the restart function is, now, in a phone menu which gives also the info about the phone (imei, firmware version and date).
  • in the cut/copy/paste system, a dialog box appears in the paste command if the file already exists to confirms its replacement.
  • when asking for 'the properties' on a folder, it gives the number of sub-folers and the number of files under the current folder.
  • when copying a file, the attributes (of the destination) are reset (eg: R/O is off if the source was on); this allows to copy files from the z: drive and delete them after.
  • when renaming a file, the old filename is displayed in the rename dialog box.
  • when a 'search for files' is performed from the root, the 'edit' menu is activated.
  • 'enter' on a drive causes an enter on this drive and 'left
    key' on a drive causes to display the properties box of this
    drive.

Version 1.06 :
  • browse thru the directories and delete/cut/copy/paste any file
  • perform a 'search files' thru the directories
  • Toggle to full screen to gain space (i.e. with no upper pane)
  • send files thru MMS, SMS, bluetooth, infrared
  • create and delete directories
  • see information (size, creation date..) of files or disks
  • view files with associated file viewer / player
  • turn the light of the display always on or off (great for the games)
  • restart the phone to the initial state
  • capture screens and save the images to a jpg file
