Carbon dioxide detectorApplication scope: Suitable for detecting CO2 concentration in industrial, agricultural, and residential environments, outputting 4-20mA analog signals and 2-channel switch signals. It can directly control the controlled equipment or output data to any electronic analog controller, DDC/PLC controller, or ventilation equipment self-control system, and control the ventilation system based on the monitored target value (CO2 concentration).
　　
Equipped with RS-485 communication interface, capable of setting independent addresses, enabling networking with computers and other control systems, and centralized intelligent management of ventilation systems in each room.
