MH-Z19 MH-Z19E IR Infrared CO2 Sensor Module For CO2 Monit

Detailed Information About The Product:

Name：MH-Z19 MH-Z19E IR Infrared CO2 Sensor Module Carbon Dioxide Gas Sensor NDIR for CO2 Monitor 400-5000Ppm UART PWM(B)
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.
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.
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 vapor interference, no poisoning
