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.
