MQ4 Gas Detection Module

MQ4 Gas Detection Module

Feature:
ICSG017A is a “Gas Sensor” module.
Size: 32mm X22mm X30mm length * width * height;
The main chip: LM393, MQ-x gas sensing probe;
Working voltage: DC 5V;
With signal output indicator light;
The dual signal output (analog output and TTL output);
The analog output and increased with the increase of concentration, the higher the concentration higher voltage;
Has a very high sensitivity to sulfide, benzene vapor, smoke and other harmful gases;
With a long service life and reliable stability;
Quick response and recovery characteristics;
With mounting holes, easy mounting;
The probe can be plug design, convenient test;

Application:
For harmful gas family, environment detection device, is suitable for the detection of the ammonia, aromatic compounds, sulfide, benzene vapor, smoke and other harmful gas, gas sensitive element concentration range: 10 to 1000ppm provides reference cases.
