Product description:
MH-Z19B carbon dioxide gas sensor is a general intelligent small sensor. It uses non-dispersive infrared (NDIR) principle to detect CO2 in the air. It has the characteristics of good selectivity, no oxygen dependence, and long life. Built-in temperature compensation; At the same time, it has serial port output and PWM output, which is convenient to use. The sensor is a high-performance sensor that combines mature infrared absorption gas detection technology with precision optical path design and sophisticated circuit design.
Sensor features:
The air chamber is gold-plated, waterproof and anti-corrosion
High sensitivity, low power consumption
Excellent stability
Temperature compensation, excellent linear output
Provide output modes such as serial port (UART) and PWM waveform
Long service life
Anti-water vapor interference, no poisoning
Main applications: HVAC equipment, air quality monitoring equipment, fresh air system, air purification equipment, smart home
