MQ3 Gas Detection Module
MQ3 Gas Detection Module-Alcohol Metal oxide sensors are also known as Chemiresistors, because sensing is based on the change of resistance of the sensing material when exposed to alcohol.
MQ3 alcohol sensor works on 5V DC and draws around 800mW. It can detect Alcohol concentrations anywhere from 25 to 500 ppm.
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.
