Product Introduction
The MWD1006 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. MWD1006 is suitable for detecting the concentration of carbon dioxide in indoor and outdoor air. MWD1006 has digital UART and PWM waveform output methods, which is convenient for application. MWD1006 has automatic zero point calibration, sensitivity calibration and clean air calibration functions. It also provides a manual calibration MCDL pin, which is for customers to use outdoor clean air to perform relative zero point calibration on the sensor module.
Main Application
MWD1006 can be widely used in air conditioning and fresh air control, indoor air quality monitoring, agricultural and animal husbandry production process monitoring. It can be installed in intelligent buildings, ventilation systems, controllers, wall-mounted applications, robots, automobiles and other applications. It can also be used in small space air quality monitoring.
