The Mikroe CO Click board utilizes the MQ-7 gas sensor, a tin dioxide (SnO2) semiconductor type. In clean air, the sensor’s conductivity is low. When carbon monoxide is present, it reacts with the sensing surface, causing a measurable increase in conductivity proportional to the gas concentration. This change is converted into a variable analog voltage signal.
The board is designed for plug-and-play compatibility with any host board featuring the mikroBUS™ standard socket, simplifying hardware integration. The included calibration potentiometer allows for fine-tuning the sensor’s output to match specific application requirements or to compensate for environmental factors, ensuring reliable performance in air quality monitoring systems, industrial safety detectors, and portable CO alarms.
