PROTRONIX NLII-RH+T-SX Room Sensor.jpg

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.

  • measures RH and temperature
  • 2x analog voltage/current output
  • SIGFOX wireless communication
  • maintenance during operation is not required

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.
For detailed information on the communication protocol, use the document NLII- Sigfox-Communication.

Sensor start after power on
All three LEDs flash simultaneously until the first readings are available, but no longer than 10 seconds.

Sensor failure indication
All three LEDs are shining permanently.

CAUTION:
Warm-up: operational after 1 minute since power on.
The declared accuracy is reached after 4 days of continuous power supply.
It is necessary to avoid severe mechanical shock of the sensor.

Factory settings

  • LED indication: by RH, indication turns off when ambient light dims
  • T analog output: voltage output
  • RH analog output: voltage output

Way to use
The product is intended for indoor use only. You can read the recommendations for sensor placement on our web pages.

End of product life
Discard the product in according to the electronic waste law and the EU directives.

Disassembly

When disassembling, be careful not to rip-out the antenna cable. It connects the antenna in lower part of the sensor with the electronics in the upper part.
