MH-Z14A CO2 Carbon Dioxide Sensor

Description:

MH-Z14A CO2 gas sensor is a general intelligent small sensor, using the non-dispersive infrared (NDIR) principle to detect carbon dioxide in air, and has a good selectivity and no oxygen dependence, long service life.It has built-in temperature compensation, as well as digital output, analog output and PWM output, convenient to use.This is a high-performance sensor combined with infrared absorption gas detecting technology, precision optical path design, excellent circuit design.

Features:

•     Gas chamber adopts gold plating processing, waterproof and anti-corrosion, long service life.
•     High sensitivity, low power consumption, excellent stability, resistant to moisture.
•     Temperature compensation, remarkable linear output(the more CO2, the higher voltage).
•     It provides a serial port (UART), analog (DAC) and PWM waveform output.
•     Widely used for heating and refrigeration equipment, air purification equipment, air quality monitoring equipment, fresh air system at smart home and school.
