Laird Sentrius™ RS1xx External RTD Temperature Probe Sensor - EU868

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 containing superior RF performance and connected to a stainless-steel probe measuring just 100 millimeters (4 inches) in length, housing a Class A tolerance PT100 RTD with a measurement temperature range of -40°C to +180°C (-40°F to +350°F) At the high end of the supported range the external temperature probe is ideally designed for monitoring low and slow cooking temps mounted inside a smoker and transmitting your data over LoRaWAN.

Equally, the probe can be used in any environment from -40°C to +180°C where a shorter, thinner stainless-steel probe would be beneficial. At its core, the RS1xx external RTD temperature sensor utilizes Laird Connectivity’s field proven and reliable RS1xx Series hardware, providing LoRaWAN options in 868, 915, and 923 MHz frequencies. The RS1xx works with Laird Connectivity’s Sentrius RG1xx Gateway for simple out-of-the-box integration and is compatible with third-party Cloud and LoRa network ecosystem partners.

This is the 915MHz variant of the RS1xx RTD sensor, we stock versions of this for different bands, and also a -100°C to +100°C probe variant. Laird's range includes the Sentrius RG1xx LoRaWAN gateways, providing a full set of hardware for cold-chain monitoring.
