Description:
The MH-Z14 carbon dioxide gas sensor is a universal smart small sensor that uses the non-dispersive infrared (NDIR) principle to detect CO2 present in the air. It is a high performance sensor with good selectivity and no oxygen dependence.
Features:
- High sensitivity, high resolution, low power consumption
- Various output methods: UART, analog voltage signal, PWM waveform
- Fast response time
- Temperature compensation, excellent linear output
- Excellent stability
- Anti-water vapor interference
