MH-Z14A is an Infrared Carbon Dioxide Sensor for accurate NDIR (nondispersive infrared) Co2 measurement using Arduino, STM32, Raspberry Pi. This NDIR Co2 sensor is a small size, common type sensor, NDIR principle to sense the presence of CO2 gas in the air. This NDIR Co2 sensor provides good selectivity, long life and non-oxygen dependent.
This MH-Z14A NDIR Co2 sensor module comes with built-in temperature compensation. MH-Z14A is a most advanced CO2 sensor that transmits a calibrated output valuein following format,
- Digital output, [Serial Port (UART, TTL level)]
- Analog Voltage output, (0.4 – 2V)
- PWM output.
This Infrared Carbon Dioxide Sensor makes it easy to measure atmospheric Co2 percentage measurement posible using Arduino code. MH-Z14A is an infrared gas sensor is developed by the deep integration of infrared absorbing gas sensing technology with the precision optical circuit.
