MH-Z19 Infrared CO2 Sensor Module for CO2 monitor

This is MH-Z19 Infrared CO2 Sensor Module for CO2 monitor. The MH-Z19 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.The built-in temperature sensor can do temperature compensation; it has digital output an analog voltage output. It is developed by the tight integration of mature infrared absorbing gas detection technology, precision optical circuit design, and superior circuit design.MH-Z19 NDIR infrared gas module is widely used in the HVAC refrigeration and indoor air quality monitoring.SpecificationsOperating Voltage (VDC)3.6 to 5.5Average Current(mA)<18Interface Level3.3VMeasuring Range0~5%VOL optionalOutput SignalPWM UARTPreheat Time(min)3Preheat Time90<60Operating Temperature (°C)0 to 50Lifespan>5Dimensions in mm (LxWxH)Weight (gm)6Shipment Weight0.01 kgFeatures :High sensitivity, high resolution.Low energy consumption.Output mode: UART and PWM wave.Temperature compensation, excellent linear output.Good stability.Long lifespan.Anti-interference of water vapor.No poisoning.Package Includes :1 x MH-Z19 Infrared CO2 Sensor Module.1 x Connecting Cable.
