GSR8 is a simple carbon dioxide concentration sensor. It converts the carbon dioxide concentration in the air to a current signal with a typified range of 4 to 20 mA and to a voltage signal a typified range 0 to 10V. The sensor can be used for a wide range of industrial control devices and control systems. Two levels of carbon dioxide concentration are signalized by LED. The levels could be setup by two trimmers.
The sensor function is based on long therm stable infrared sensing element. GSR8 sensors are mainly used for air condition control systems or for CO2 leak detection in storage.
