MQ-4 Methane Gas Sensor Module MQ 4

MQ-4 Methane Gas Sensor Module MQ 4
Sensitive material MQ- 4 gas sensors used in clean air, low conductivity tin oxide (SnO2). When there is an environment in which the combustible gas sensor, conductivity sensor with increasing concentration of combustible gases in air increases. Use simple circuit can convert the change in conductivity of the gas concentration corresponding to the output signal. MQ-4 Methane gas sensor of high sensitivity, propane, butane and has a good sensitivity. The sensor can detect a variety of combustible gases, especially natural gas, it is a low-cost sensor suitable for a variety of applications.


1, Ukuran: 32mm X22mm X24mm

2, chip utama: LM393, sensor gas MQ-4
3, tegangan kerja: DC3-5V
4, dengan instruksi keluaran sinyal;
5, output ganda (output analog, dan output level TTL);
6, TTL output sinyal yang valid rendah, mikrokontroler dapat dihubungkan secara langsung;
7, 0 ~ 5V tegangan keluaran analog, semakin tinggi tegangan semakin tinggi konsentrasi;
8, uap etanol dengan sensitivitas tinggi dan selektivitas yang baik;
9, dengan umur panjang dan stabilitas yang dapat diandalkan;
10, karakteristik respon cepat;
11, Aplikasi:
Untuk gas metana rumah, pabrik, gas alam, dan perangkat pemantauan lainnya untuk menguji gas alam, metana 300 hingga 10000ppm

Wiring: 
++ VCC: positive power supply (5V) 
++ GND: power supply is negative 
++ DO: TTL switching signal output 
++ AO: analog signal output 

Special note: After the sensor is powered,needs to warm up around 20Sec, measured data
