Room sensor NLII-RH+T-R is used to monitor the air quality inside buildings and power control ventilation (HVAC) systems according to current levels of air pollution. The sensor measures the relative humidity (RH) and temperature (T). It is suitable for living rooms, bathrooms, warehouses, ateliers etc.
Measurement of the relative humidity is based on the principle of capacitive polymer sensor. The sensor has two built-in separate analog outputs – one for the actual concentration of relative humidity and the other for the current temperature. Sensor also contains one relay, it’s response – RH or temperature – can be set by shorting jumper. Level of air quality at which the relay switches can be easily adjusted by the rotary switch.
Current air quality can be easily checked the by three LED indicators. Eco level means good indoor air quality needed to achieve a sense of well-being together with optimizing energy costs for heating or air conditioning.
