Decentlab‘s surface temperature sensor uses LoRaWAN® technology to measure thermal energy with great accuracy. Enabling remote temperature monitoring, the surface temperature sensor is ideal for applications such as; road surface monitoring, ice warnings and smart agriculture.

With an adjustable measuring area, users can alter the area based on the distance between the target and sensor lens:

Distance Measuring Spot Diameter
100 mm 11.6 mm
400 mm 26.7 mm
1000 mm 76.5 mm
2000 mm 160 mm
5000 mm 409 mm

Sensor data is transmitted at configurable intervals via LoRaWAN® which is then sent to a compatible gateway over a range of up to 10 km.


  • LoRaWAN® Compatible
  • Accuracy measured to +1.5% or +1.5°C
  • Adjustable monitoring area
  • Wireless range up to 10 km (line of sight), approx 2 km (suburban areas)
  • Up to 8.5 years battery life (dependent on interval settings)
