The MWD1006L is a gas detection module based on the NDIR infrared absorption technology. It uses a single light source and a single-channel detector. The sampling method use self-diffusing. MWD1006L is suitable for detecting carbon dioxide concentration in indoor and outdoor air.
MWD1006L can be widely used in air conditioning and fresh air control, indoor air quality monitoring, agricultural and animal husbandry production process monitoring, and can be installed in intelligent buildings, ventilation systems, controllers, wall mounted application, robots, automobiles and other applications. It can also be used for air quality monitoring in small spaces.
● Zero point self-calibration function
● Ultra-low power consumption
● Anti-interference from moisture
● Multiple output interfaces selection: UART, PWM , IIC and analog voltage output (adjustable)
● Wide temperature compensation range
