Voltage output of carbon dioxide / CO2 sensor module MH-Z19A of small size

 

Applications

MH-Z19A, Voltage output of carbon dioxide / CO2 sensor module MH-Z19A of small size NDIR infrared gas module is widely used in the HVAC refrigeration and indoor air quality monitoring.

 

Profile

 

MH-Z19A, Voltage output of carbon dioxide / CO2 sensor module MH-Z19A of small size, NDIR infrared gas module is a common type, small size sensor, using non-dispersive infrared (NDIR) principle to detect the existence of CO 2 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.
