Product Introduction
The MWD1006E 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. MWD1006E is suitable for detecting carbon dioxide concentration in indoor and outdoor air.
Various output methods can be used such as digital UART, analog voltage and PWM waveform output, which is convenient for application. MWD1006E has automatic zero point calibration, sensitivity calibration and clean air calibration functions. It also provides MCDL pin for manual calibration, which is for customers to use outdoor clean air to perform relative zero point calibration on the sensor module.
MWD1006E 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.
Module Characteristics
● Zero point self-calibration function
● Ultra-low power consumption
● Multiple output interfaces selection: UART, PWM and analog voltage output (adjustable)
● Wide temperature compensation range
