Sensor Interface / PT100 RTD Sensor Node

PT100 RTD Sensor Node

The PT100 RTD Sensor Node enables precise temperature monitoring using a variety of sensors. 

It uses the integrated radio transceiver to report its measurements through Senceive’s wireless communications network to a Gateway.

Typical temperature monitoring applications:

  • Steel structures
  • Rail, for critical rail temperature alerting
  • Concrete structures, including during curing
  • Heating, ventilation, and air conditioning (HVAC) systems
