The MQ-7 Carbon Monoxide Gas Sensor Module is designed to detect CO (carbon monoxide) gas concentrations in the air. It is ideal for use in gas leakage detection systems, industrial safety applications, and air quality monitoring.
This sensor provides both analog and digital output signals, making it compatible with Arduino, Raspberry Pi, ESP32, and other microcontrollers. It has a high sensitivity to carbon monoxide (CO) and can detect concentrations ranging from 10 to 10,000 ppm.
The MQ-7 module includes a preheat cycle to enhance accuracy and an onboard potentiometer to adjust sensitivity. It operates by cycling between two voltage levels, detecting CO more effectively.
