Sentrius RS1xx Series

Module with LoRa + Central or Peripheral BLE

Made by
Laird is a certified partner.


The Sentrius™ RM1xx series of modules offer a powerful, convenient solution for long-range Enterprise IoT (EIoT) deployments. Laird innovatively combines Bluetooth® v4.0 with LoRaWAN™, the emerging standard in Low Power Wide Area Networks (LPWAN) into one module. RM1xx modules aggregate and transmit data from Bluetooth® Smart (BLE) devices and sensors over LoRaWAN to gateways as far as 15 km (~10 miles) away. This bridges the personal area network to the wide area network in a unique way. The Sentrius RM1xx will be LoRa® Alliance certified and fully interoperable with any LoRaWAN™-adherent gateway.
