MH-Z19 NDIR CO2 Sensor

MH-Z19 NDIR infrared gas module is a common type, small size sensor, using non-dispersive infrared (NDIR) principle to detect the extensce of CO2 in the air, with good selectivity, non-oxygen dependent & long life. Built-in temperature sensor can do temperature compensation, & it has digital output & analog voltage output. It is developed by the tight integration of mature infrared absorbing gas detection technology, preicsion optical circuit design & superior circuit design.
