Rancangan Alat Ukur Suhu Ekstrim Secara Telemetri Berbasis Atmega8 dan Tampilan Pada PC

Abstract

This study was design to make an air temperature measuring devices which can observations automatically and monitored from afar places with an alarm as a warning in case of extreme temperatures. This instrument consists of three main components namely LM sensor 35 as a temperature sensor, ATMega8 as a microcontroller, and Transmitter-Receiver modules as components telemetry equipped with an alarm (LED and buzzer) as a warning indicator when extreme temperatures occur. This instrument has been tested and works fine. The measuring instrument data validation has been carried out on standard tool (which was traceable to national and international standards). And obtained the measuring instrument error of + 1.024%. With the design of the system in extreme temperature measuring devices is expected ATMega8 telemetry-based air temperature observation can be done more effectively and efficiently.
