GMH-Z19D NDIR infrared CO2 sensor module is a common type, small size sensor, pins type or terminal type, using non-dispersive infrared (NDIR) principle to detect the existence of CO2 in the air, with good selectivity, non-oxygen dependent and long lif e. Builtin temperature compensation; and it has UART output and PWM output. It is developed by the tight integration of mature infrared absorbing gas detection technology, precision optical circuit design and superior circuit design.
*High sensitivity, low power consumption
*Good stability
*Temperature compensation, excellent linear output
*Multiple output modes: UART, PWM
*Long lifespan
*Anti-water vapor interference, anti-poisoning
Main Applications:Indoor air quality monitoring / HVAC refrigeration / Ventilation system / Air cleaner device
