Product Details
MH-Z19C carbon dioxide gas sensor (hereinafter referred to as sensor) is a general intelligent small sensor, which uses the principle of non-dispersive infrared (NDIR) to detect CO2 in the air. It has good selectivity, no oxygen dependence, long life, etc.; built-in temperature compensation; serial output, analog output, PWM output, easy to use. This sensor is a high-performance sensor made by combining mature infrared absorption gas detection technology with precise optical path design and excellent circuit design.
Product Features
The air chamber is gold-plated
Provides serial port (UART), PWM waveform and other output methods
Anti-water vapor interference, no poisoning, long service life
Product Applications
Main applications: HVAC equipment, air quality monitoring equipment,
fresh air system, air purification equipment, smart home, school
