Desain Alat Pendeteksi Kebocoran Gas LPG Menggunakan Sensor MQ-6 Berbasis ATMega8

Abstract

Sensor MQ 6 is a gas sensors are used to detect LPG, iso-butane, propane with high sensitivity. Gas sensor MQ-6 has a small sensitivity to a drug alcohol and cigarette smoke. Gas sensor MQ-6 is a sensor that has a rapid response to the LPG / Liquid Petroleum Gas, stable and durable, and can be used in a simple drive circuit. The sensor was developed by micro Al2O3 ceramic tube, Tin Dioxide (SnO2) sensitive layer, measuring electrode and heater are fixed into a layer of skin created by plastic and stainless steel net. What was detected sensor will be forwarded to the ATmega8 as a control center which causes the buzzer sounds a sign of gas being detected and will be forwarded to the LCD for menampilakan the measurement and display of some description. LCD is directly connected to Port B of the microcontroller serves to send the data processing results to be displayed in the form of alphabet and numeric LCD.
