Holosys LoRaWAN™ Temperature Sensor WTS-L

  • Environment temperature accurate measurement
  • Equipped with temperature sensor probe on a cable
  • Battery powered device with autonomous operation up to 15 years LoRaWAN™ v1.0.2 communication protocol
  • Operating frequency 868 MHz
  • Wide temperature range measurement (-10°C ... +85°C)

Holosys LoRaWAN™ Temperature Sensor WTS-L is a device that provides wireless temperature measurement via radio telegrams according to the LoRaWAN™ v1.0.2 communication protocol.


The device is equipped with temperature sensor probe on a cable and provides accurate environment temperature measurement (±0.5°C accuracy in -10°C ... +85°C temperature range). Besides temperature, it can optionally read two digital inputs (CH1 and CH2) states.


LoRaWAN™ v1.0.2 communication protocol ensures compatibility with a wide range of the equipment.
