This semiconductor gas sensor detects the presence of Carbon Monoxide at concentrations from 10 to 1,000 ppm and combustible gas from 100 to 10,000 ppm. The sensor’s simple analog voltage interface requires only one analog input pin from your microcontroller.
This product has the MQ sensor carrier board included. Works with 5V and has TTL level digital and analog outputs which makes it very easy to use with Arduino and other microcontrollers.
Dimensions: 32 x 20 x 22mm
