Digital CO sensor model for carbon monoxide Introduction The M1003 carbon monoxide gas sensor module is a module developed using a MEMS micro gas sensor that can be used to detect the CO gas content in the air. The module is extremely sensitive to CO gases and excludes interference from high concentrations of alcohol. Main Feature High sensitivity, high resolution, low power consumption, long service life, UART, analog voltage signal, PWM waveform and other output methods, high stability, excellent anti-interference ability (6000ppm alcohol), excellent linear output. Technical Parameter

Remarks: Pin 1 of the CO alarm state outputs a 1KHZ waveform, and pins 5 and 6 directly output a high level. During preheating, pin 8 switches at a high and low frequency of 1HZ. After preheating, the normal operation is normal high level. Pin 7 is a fault alarm signal light. If there is a fault, pin 7 outputs a high level. Other unused pins can be added according to the actual needs of the user. If output signals such as buzzers, relays, solenoid valves are required, they can be directly noted when placing an order. UART communication setting parameters 1. General settings: Use UART communication...

sensitivity characteristics to decrease and affect the measurement accuracy of the module. 1.4 Icing The icing on the surface of the sensor's sensitive material of the module will cause the sensitive layer to crack and lose its sensitive characteristics. 2 Conditions to avoid as much as possible 2.1 Condensate Under indoor use conditions, slight condensation of water will have a slight impact on the sensor performance in the module. But if water condenses on the surface of the sensitive layer And hold it for a period of time, the sensor characteristics in the module will decrease, and the measurement...
