Veinasa-THCO2 Indoor Air Quality Digital Carbon Dioxide Temperature Humidity Ndir Sensor CO2 Temperature Humidity Sensor
This sensor using imported sensor chip for detection of CO2 concentration, air temperature and humidity in various environment, which has the characteristics of high precision and good stability.
The corresponding signal transducer adopts advanced integrated circuit module, according to different needs, it can be converted to the corresponding voltage or current signal. The utility model has the advantages of small size, convenient installation, portability, reliable performance, good linearity, strong load capacity, long transmission distance and strong anti-interference ability.
It can be widely used in the detection of carbon dioxide concentration, air temperature and humidity in office buildings, public places, greenhouse, production plants and other outside places.
