With strong selectivity, non-oxygen dependence, and a long lifespan, the Winsen MH-Z19Z19C NDIR CO2 Sensor infrared gas module is a common type of tiny sensor that uses non-dispersive infrared (NDIR) principle to detect the existence of CO2 in the air. It includes PWM and UART outputs in addition to built-in temperature adjustment. It is created through a close combination of excellent circuit design, precise optical circuit design, and established infrared absorbing gas detection technology.
