WSDMAVIS 1Pcs MiCS-5524 Gas Sensor Module for CO Natural Gas Leakage Detection Alcohol VOC Gas Sensor Module

The MiCS-5524 is a robust MEMS sensor for indoor carbon monoxide and natural gas leakage detection. It's suitable also for indoor air quality monitoring and early fire detection. Power it with 5 VDC and read the analog voltage off of the output pin. When gasses are detected, the analog voltage will increase in proportion of detected gas. When powered, the heater draws about 25-35mA. You can use the EN pin to power it off (pull it high to 5V to turn off) to conserve energy. Just make sure to wait a second after turning the heater on to make sure its all heated before taking readings. Please note: This sensor is sensitive to CO ( ~ 1 to 1000 ppm), Ammonia NH3 (~ 1 to 500 ppm), Ethanol C2H5OH (~ 10 to 500 ppm), Hydrogen H2 (~ 1 - 1000 ppm), and Methane CH4 (~ 1,000++ ppm). However, it can't tell you which gas it has detected., Weight: 0.0440924524 pounds, Manufacturer: WSDMAVIS
