Sentrius RS1xx LoRa-Enabled Sensors


The Sentrius™ RS1xx LoRa-Enabled Sensor from Laird is a battery powered, long range integrated sensor platform leveraging the benefits of LoRaWAN and Bluetooth Low Energy (BLE) connectivity. Its small, rugged form factor contains superior RF performance and flexibility with precise temperature and humidity sensors, and room for future expansions. At its core, the Sentrius™ RS1xx utilizes Laird’s field-proven and reliable Sentrius™ RM1xx module hardware, providing LoRaWAN options in 868 and 915MHz frequencies, plus BLE for local data display, configuration and troubleshooting. Based on the Semtech SX1272 and Nordic nRF51 silicon, it offers a LoRa range up to 10 miles with a local 2.4 GHz connectivity option to smartphones and tablets. The Sentrius™ RS1xx Series works with Laird’s Sentrius™ RG1xx Series of LoRa / multi-wireless gateways for simple out-of-the-box integration, and is compatible with 3rd party cloud and LoRa network ecosystem partners.

  • Multi-wireless: LoRaWAN (868 / 915 MHz) and Bluetooth v4.2 (Central / Peripheral) with fully integrated high performance antennas 
  • Multi sensor: Temperature & Humidity, (future options for a range of additional sensors via expansion port) 
  • Fully certified for FCC, CE, IC, and Bluetooth SIG
  • Simple wireless configuration using mobile application and BLE. 
  • Harsh Environments: Rugged enclosure serves many varied installation needs 
  • Integrated out of the box networks: Default configuration with Laird Sentrius™ RG1xx gateways for simple, out-of-the-box cloud connectivity.
