The MQ7 carbon monoxide sensor is a compact and efficient device designed to detect the presence of carbon monoxide (CO) gas in the air. It is particularly sensitive to CO, a colorless and odorless gas that can be harmful or even fatal if inhaled in high concentrations. The sensor operates on the principle of chemoresistance, where the electrical resistance of the sensor changes when it comes into contact with CO gas. This change in resistance is then measured to determine the concentration of CO present in the air.
The MQ7 sensor is known for its quick response time and high sensitivity, making it a reliable choice for monitoring CO levels in various environments.
