| Product Introduction
The WCGS300 series indoor carbon dioxide sensor developed and produced by winchen is an intelligent CO2 transmitter for indoor air quality monitoring and ventilation control. Using the non-dispersive infrared (NDIR) detection principle, it measures the carbon dioxide concentration in the air in real time. It supports optional one-channel RS485, 4-20mA or 0-10V output plus one relay output, wall mounting, and optional LCD display. It can be linked with fresh air systems, air conditioners, air purifiers and intelligent building automation systems to automatically adjust ventilation volume according to CO2 concentration, improving indoor air quality while reducing energy consumption. It is suitable for indoor environments such as offices, meeting rooms, classrooms, shopping malls, hotels, hospitals and residences, and can also be used for CO2 concentration monitoring in greenhouses, breeding facilities, underground spaces and other scenarios.
