MH-Z19 MH-Z19E IR Infrared CO2 Sensor Module Carbon Dioxide

Detailed Information About The Product:

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
