MH-Z18 Min Infrared Gas Module Group CO2 Detection Sensor Module
Description:
- MH-Z18 NDIR infrared gas module is a small general-purpose, small sensors, the use of non-dispersive infrared (NDIR) principle of the CO2 present in the air detect, with good selectivity, without oxygen dependence, and long life. Built-in temperature sensor, temperature compensation; also has a digital output and analog voltage output, easy to use. MH-Z18 is a mature infrared absorbing gas detection technology and precision optical design, sophisticated circuit design closely integrated to produce a universal infrared gas sensor.
Can be widely used in HVAC and indoor air quality monitoring, industrial process monitoring and security, agriculture and livestock production process monitoring.
