DETEKSI KEBOCORAN GAS LPG BERBASIS MIKROKONTROLER ATMega8535

Abstract

Abstract. An electronic system based on Atmega8535 microcontroller for detecting LPG gas has been done. The system was employed a gas sensor, a temperature sensor DS18S20, Op-amp LM358, IC voice ISD25120, a microcontroller, and LCD display. The microcontroller was programmed with Basic program that suitable for the device. The system was supported a gas sensor and a temperature sensor to get the main signal the gas available on air surrounded gas tube and temperature condition. All of the system was controlled by microcontroller. The signal from the microcontroller is send to LCD and IC vice ISD 25120. It was concluded that the system work well well since the all parameter were displayed on monitor simultaneously. Keywords: ATMega8535, sensor DS18S20, ISD25120
