Room sensor NLII-RH is used to continuously
monitor the air quality inside buildings and
then 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.

Description
Measurement of the relative humidity is based on the
principle of capacitive polymer sensor.
The sensor has built-in two separate analog outputs -
one for the actual temperature and the other for the
actual relative humidity.
Sensor can efficiently manage ventilation and heat
recovery units, based on current air quality.
The current air quality can easily be determined by
looking at the three LED indicators. The
eco level
means good indoor air quality that is needed to achieve
a sense of well-being and at the same time optimal
energy costs for heating or air conditioning.
