The MQ7 Gas Sensor Module is a Carbon Monoxide (CO) sensor suitable for sensing CO concentrations in the air. It can detect CO-gas concentrations anywhere from 20 to 2000 ppm.It make detection by method of cycle high and low temperature, and detect CO at low temperature.It is widely used in domestic CO gas leakage alarm, industrial CO gas alarm and portable CO gas detector. The sensor can measure concentrations of 10 to 10,000 ppm.
