MH - Z19 C02 gas sensor is a common type, small sensors, using the non-dispersive infrared (NDIR) principle to detection of our fleet in the air, has good selectivity, no oxygen dependence, long life, built-in temperature compensation: lotus digital output and waveform output at the same time, easy to use. The sensor is a high performance sensor which combines mature infrared absorption gas detection technology with precision light path design and sophisticated circuit design.
This MH - Z19 C02 gas sensor has high sensitivity, high resolution.
Providing a variety of forms output modes, such as UART and PWM wave.
Anti-water vapor interference, no poisoning.
With temperature compensation, excellent linear output.
Low power consumption, good stability and long lifespan.
It is widely used in the HVAC refrigeration and indoor air quality monitoring.
