Overview :
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.
Feature:
- High sensitivity, low power consumption
- Excellent stability
- Temperature compensation, excellent linear output
- Provide serial port (UART), PWM waveform and other output methods
- Anti-water vapor interference, no poisoning
Application:
HVAC equipment
Air quality monitoring equipment
Fresh air system
Air purification equipment
Smart home
