This is a module of a high sensitive MQ7 gas sensor. It detects the presence of carbon monoxide (CO) coal gas in the air from 10 ppm to 10000 ppm. 

The module is quite simple to use and interface with any controller like Arduino, Raspberry Pi, AVR, etc. It provides an analog output corresponding to the concentration of the gases in the air and an easy to use digital output. The device requires minimal external components, just connect the VCC and GND and you are ready to go. It has a potentiometer onboard that can be used to adjust the threshold level of the output.
