MH-Z19E CO2 Sensor Module Carbon Dioxide Gas Sensor For CO2 Monitor 400-5000ppm UART PWM Output

Product Details:

The MH-Z19E carbon dioxide gas sensor (hereinafter referred to as the sensor) is a general-purpose intelligent small sensor. It has two products: pin and terminal. It uses the principle of non-dispersive infrared (NDIR) to detect CO2 in the air and has good selectivity. , No oxygen dependence, long life, etc.; built-in temperature compensation; also has serial port output, PWM output, easy to use. The sensor is a high-performance sensor made by closely combining mature infrared absorption gas detection technology with precise optical circuit design and sophisticated circuit design. Sensor characteristics: High sensitivity, low power consumption Excellent stability Temperature compensation, excellent linear output Provide serial port (UART), PWM waveform and other output methods long lasting Anti-water interference, no poisoning Application: HVAC equipment Air quality monitoring equipment Fresh air system Air purification equipment Smart home school Parameters: Product model: MH-Z19E Detection gas: carbon dioxide Power supply voltage: DC(5.0±0.1)V Average current:
