LoRawan Indoor Temperature & Humidity Sensor


£122.57 (£102.14 ex VAT)

The sensor measures the ambient temperature and relative humidity in buildings, apartments, houses.
It transmits the data via a public or private LoRaWAN™ radiofrequency network.

Features:

  • LoRaWAN™, Class A
  • Easy to install and use
  • Up to 10 years autonomy
  • Temperature and Humidity measure
    – Range : 0°C / +40°C ; 0%rH / 100%rH
    – Accuracy: +/-0,3°C ; +/-3%rH
    – Resolution: 0,2°C ; 0,5%rH
  • Data compression for batch report

 The sensor measures temperature and relative humidity indoors. Data transmission on public or private LoRaWAN® network is done periodically or immediately in case of alert: 

Exceeding of thresholds Minimum or maximum temperature. 

Minimum and maximum humidity thresholds exceeded. 

Sensor unclipped from its wall mounting. Installation and commissioning are quick and easy. The sensor is equipped with: 

a switch (ILS) for activation and deactivation, 

LEDs to monitor the configuration and association on the network. Each sensor is identified by a QR code on the label and an NFC tag in the box. 

The measurement data is transmitted individually or aggregated and compressed (batch mode) before being transmitted on the LoRaWAN® network. Batch mode significantly reduces the amount of data transmitted while preserving the sensor’s autonomy. Powered by a 3.6V/2500mAh battery, the sensor’s autonomy is over 8 years with a configuration of 2 measurements and 2 transmissions per day. The battery voltage level can be regularly monitored remotely
