LoRaWAN® Winter Road Maintenance Sensor

Add to Quote


The Decentlab Winter Road maintenance sensor combines air temperature, humidity and infrared surface temperature sensors in one device. Providing high accuracy air temperature measurements between ±0.1°C (20 – 60°C); ±0.2°C (-40 – 90°C) and high accuracy air humidity measurements between ±1.5 % (0 – 80 %); ±2 % (80 – 100 %) RH.

This contactless surface temperature sensor (pyrometer) is compatible with LoRaWAN® networks of any provider. Simply place and measure; no setup required.

Ideal for applications such as:

  • Winter road maintenance
  • Frost and ice alerts
  • Smart Agriculture

The Winter Road Maintenance sensor is configurable via command line interface and downlink command interface this sensor can be left unattended for several years without replacing the batteries.

Housed in a robust polycarbonate enclosure, this device is weatherproof, impact and UV-resistant with an IP67 rating.

This sensor is available in two variants, DL-WRM-001 features a bare sensor head whereas the DL-WRM-002 features weather protection and a mounting kit.
