20210324· Features about calibration (both MHZ19 MHZ19B), detection range change (MHZ19B) and ABC logic on/off(MHZ19B) are implemented at version or later. I''m afraid I''ve just only implemented these without test due to lack necessary devices and apparatus for the test, fx: standard concentration CO2 gas, also MHZ19B module.


Intelligent Infrared CO2 Module (Model: MHZ19)

MHZ19 NDIR infrared gas module is a common type, small size sensor, using nondispersive infrared (NDIR) principle to detect the existence of CO 2 in the air, with good selectivity, nonoxygen dependent and long life. Builtin temperature sensor can do temperature compensation; and it has UART output and PWM output. It is developed by the tight integration of mature infrared absorbing gas ...
