MH-Z16 Infrared CO2 Gas Module
Profile
MH-Z16 NDIR Infrared gas module is a common type, small size sensor, using non-dispersive infrared (NDIR) principle to detect the existence of CO2 in the air, with good selectivity, non-oxygen dependent and long life. Built-in temperature compensation; and it has digital output and PWM wave output. This common type infrared gas sensor is developed by the tight integration of mature infrared absorbing gas detection technology, precision optical circuit design and superior circuit design.
Main features
- High sensitivity, Low power consumption
- Good stability
- Temperature compensation, excellent linear output
- Output method: UART, PWM
- Long lifespan
- Anti-water vapor interference, no poisoning
Application
- animal husbandry production
- educational instruments
- indoor air quality monitoring equipment
- HVAC equipment
- air purification equipment

Cautions
- Please avoid the pressure of its gilded plastic chamber from any direction, during welding, installation, and use.
- When placed in small space, the space should be well ventilated, especially for diffusion window.
- The module should be away from heat source, and avoid direct sunlight or other heat radiation.
- The sensor should be calibrated regularly and the calibration cycle is recommended for no more than 6 months.
- Do not use the sensor in the high dusty environment for long time.
- To ensure the normal work, the power supply must be within DC (5.0±0.1)V rang, the power current must be not less than 150mA. Out of this range, it will result in the failure of the sensor. (The concentration output is low or the sensor cannot operate properly)
- During manual zero calibration, the sensor must work in stable gas environment (400ppm) for over 20 minutes.
