Principle Introduction:
MH-Z19Z19C NDIR infrared gas module is a common type, small size sensor, using non non-di spersive infrared (NDIR) principle to detect the existence of CO2 in the air, with good selectivity, nonnon-oxygen dependent and long life. Built Built-in temperature compensation; and it has UART output and PWM output. It is developed by the tight integration of m ature infrared absorbing gas detection technology, precision optical circuit design and superior circuit design.
Applications :
MH-Z19C NDIR infrared gas module is widely used in
* HVAC refrigeration
*Indoor air quality monitoring.
*Smart home appliances
*School
*Air cleaner
