MQ7 Gas Detection Module
MQ7 Gas Detection Module is CO2, which with lower conductivity in clean air. It make detection by method of cycle high and low temperature, and detect CO when low temperature (heated by 1.5V). … When high temperature (heated by 5.0V), it cleans the other gases adsorbed under low temperature
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;
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.
