Description: This module is based on the MiCS-5524 chip that is a robust MEMS sensor for carbon monoxide and natural gas leakage detection. It is suitable for air quality monitoring, breath checker and early fire detection which can be used for both indoor and outdoor environments. These sensors can be built at home or bought from certain manufacturers. Here are the steps to use MiCS-5524 sensor: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 the 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 for a second after turning the heater on to make sure it is all heated before taking readings.
