Description :Telah dibuat prototipe telemetri berbasis mikrokontroler dengan
pengiriman data melalui WiFi untuk mendeteksi dan merekam suhu permukaan
fluida seperti air laut, sungai atau cairan dalam pipa-pipa atau tandon pada
industri tertentu. Metode pengambilan data dilakukan secara time series atau
kontinue terhadap waktu. Sensor yang digunakan adalah LM35 dan telah diuji
coba pada range 270C 1000C dengan total error instrumen sebesar 1,38%.
Selanjutnya informasi yang diperoleh dari sensor dikirim ke receiver
melalui komunikasi yang dilakukan secara wireless dengan gelombang RF pada
frekuensi 2,4 GHz. Sensor ini terhubung dengan mikrokontroler dan modul
transciever yang akan mengirimkan data melalui WiFi ke modul transciever lainyang terhubung dengan komputer sebagai receiver. Mikrokontroler disini
berfungsi sebagai interfacing pengolah data antara sensor dan kanal RS232.
Sedangkan komputer untuk monitoring dan penyimpan data. Dari hasil
penelitian, transmisi data dapat dilakukan secara wireless sampai jarak 150 meter.
Alat ini diusulkan dapat diterapkan dalam bidang oceanografi untuk sensing
temperatur muka laut sebagai deteksi dini terjadinya bencana, posisi ikan, dan
untuk aplikasi di bidang industri.
Description Alt:
The telemetry prototype that used for transferring and recording
temperature data of fluid surface was design and fabricated. Wireless
communication between two AVR microcontroller are tuned to work correctly at
2,4 GHz using transceiver modules. The transceiver modules can be powered by
5V power supply which is common for AVR microcontrollers without problem in
interfacing. Modules do not require addition components, just apply power and
connect data line to send information to/from and thats it.
The temperature sensor that used in this application is LM35, that is
precision integrated-circuit temperature sensors, whose output voltage is linearly
proportional to the Celsius (Centigrade) temperature. The wireless
communication can transfer the data temperature less than 100 0C for distances
150 meters.This prototype can be applied to detect the sea surface temperature, fish
position, and for other industrial application.
