    FAQ
    ❯

    A carbon monoxide (CO) sensor module is a compact device designed to detect the concentration of CO gas in the air. It converts the detected gas concentration into an electrical signal that can be read by a microcontroller or monitoring system, enabling safety control and alarm functions.

    ❯

    The CO sensor module typically employs electrochemical or semiconductor sensing elements. When CO molecules contact the sensor surface, a chemical reaction generates a weak current proportional to the gas concentration, enabling precise real-time detection.

    ❯

    CO sensor modules are widely applied in residential gas alarms, parking garages, industrial gas monitoring systems, and smart IoT safety devices to prevent poisoning and ensure air safety.
