Laird Sentrius™ RS1xx Cold Chain Temperature Probe Sensor - EU868:

Laird's Sentrius RS1xx Temperature Probe Sensor is an industrial grade sensor, ideal for cold-chain applications. Designed to be wall-mounted, or fitted inside fridges and freezers, the sensor monitors the environment and ensures compliance with HACCP food safety regulations. The unit can be installed in walk-in refrigerators and freezers or cold rooms, in shops, restaurants, and more.

The sensor is bundled with an external temperature probe idea for reaching the middle of food containers, or inside fridge doors. The probe is 213mm long and has a 1.3m long cable to give many installation options.

Powerful features include storage of data on the sensor when the LoRaWAN network isn't available, to be retrieved later when connectivity is restored. This helps to maintain a complete record of readings, even during power or network outages

Configuration of the sensor is made easy with Laird's Sentrius Sensor app for Android and iOS. Connecting via Bluetooth it allows configuration of measurement/transmission intervals and LoRaWAN keys. It's also possible to view historic stored measurements, and perform firmware updates.

This is the 868MHz variant of the RS1xx, we stock versions of this for different bands, and an external probe variant. Laird's range includes the Sentrius RG1xx LoRaWAN gateways, providing a full set of hardware for cold-chain monitoring.

Key Features:

  • EU868 LoRaWAN band
  • Bluetooth 4.2 for configuration
  • IP65 waterproof enclosure, with breathable sensor cover
  • Powered by 2x AA Alkaline or Lithium batteries
  • 256k of flash memory to store readings
  • Robust mounting lugs
