MH-Z19C NDIR CO2 Sensor for HVAC and IAQ

Principle Introduction:
MH-Z19C NDIR infrared gas module is a common type, small size sensor, using non-dispersive infrared (NDIR) principle to detect the existence of CO2 in the air, with good selectivity, non-oxygen dependent and long life. Built-in 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. MH-Z19C is affordable for RESET standard.

Applications :
 MH-Z19C NDIR infrared gas module is widely used in
*HVAC refrigeration
*HVAC control panel/Thermostat
*Indoor air quality monitoring.
*Smart home appliances
*Air purification equipment
*CO2 detector/Monitor
