Laird Sentrius™ RS1xx External RTD Temperature Probe Sensor

Laird Connectivity’s Sentrius RS1xx external RTD temperature probe is a battery-powered, long range sensor platform that leverages the benefits of LoRaWAN and Bluetooth Low Energy (BLE) connectivity.

Packaged in a small, rugged form factor, the sensor unit connects to a PT100 sensor for wide temperature range sensing. The external probe is stainless-steel, housing a Class A tolerance PT100 RTD with a measurement temperature range of -100°C to +450°C (-40°F to +842°F), depending on the probe chosen.

At the high end of the supported range the external temperature probe is ideally designed for monitoring cooking in pizza ovens and fryers, and high temperature industrial processes.

The medium range probes support monitoring in HVAC systems, cooking temperature compliance, and the low-temperature range is ideal for fridges and freezers. The low-temperature probe reaches down to -100°C, ideal for cold-chain applications such as food safety, vaccine storage and industrial cooling.

This is the US915 band variant of the RS1xx RTD sensor, we stock versions of this for different bands. Laird's range includes the Sentrius RG1xx LoRaWAN gateways and various RS1xx sensors, see all Laird's products.
