MQ7 Carbon Monoxide Gas Sensor Module is used to detect Carbon Monoxide (CO) concentration, it can detect CO-gas concentrations anywhere from 20 to 2000 ppm. This sensor has a high sensitivity and fast response time. The module outputs a voltage from 0 to 5V relative to the CO concentration.
- High sensitivity to carbon monoxide.
- Stable and long life.
- They are used in gas detecting equipment for carbon monoxide(CO) in family and industry or car.
