MH-Z14A NDIR PWM CO2 Sensor - Infrared Carbon Dioxide Sensor

MH-Z14A CO2 gas sensor uses the non-dispersive infrared (NDIR) principle to detect carbon dioxide in the air. It is a general intelligent small sensor using and has good selectivity and oxygen dependence, long service life. It has digital output, analog output and PWM output, as well as internal temperature compensation. This is a high-performance sensor combined with infrared gas detection technology, precise optical path design, excellent circuit design.

Waterproof and anti-corrosion, long life
High sensitivity , low power consumption, excellent stability, moisture resistant
Temperature compensation, outstanding linear output (more CO2, higher voltage)
Serial port (UART), analog (DAC) and provides PWM waveform output
Widely used for heating and cooling equipment, air purification equipment, air quality monitoring equipment, fresh air system in smart home and school
