Designed for cold-chain management applications such as agriculture and food safety monitoring, the Sentrius RS1xx external series probe from Ohio-based Laird Connectivity is said to make it easy to monitor environmental data.
The sensor has integrated antennas, an external temperature probe and rugged IP65 enclosure. The probe lets users mount the sensor outside of a device and measure the temperature inside via the cabled sensor. The rugged and configurable sensor device leverages the benefits of LoRaWan and Bluetooth Low Energy connectivity in a small form factor.
The probe can be coupled with a Sentrius RG1xx LoRa gateway to deliver a wireless ecosystem with improved RF performance. This ecosystem of pre-integrated products provides developers and OEMs with the flexibility and freedom to create everything from a single stand-alone node to a complete end-to-end IoT network.
"The RS1xx series platform enables enterprise customers to deploy secure, stable wireless sensors in long-range IoT applications," said Jonathan Kaye, product director for Laird Connectivity. "Ideal for monitoring and measuring liquid temperature, the durable external probe gives customers more flexibility, as it can be built into a system or used as an aftermarket solution."
The probe supports a temperature range of -55 to +125˚C. It sends sensor data in harsh RF environments over long distances to remote LoRaWan gateways and, with the added benefit of a BLE connectivity option, sensor data can be sent to smartphones and tablets for local configuration, control or data visualisation.
Pairing the RS1xx with the other elements of Laird Connectivity’s growing LoRaWan products ecosystem enables cost-effective and end-to-end control of public and private LoRaWan networks. The RS1xx works with Laird’s RG1xx series of LoRa and multi-wireless gateways for out-of-the-box integration and is compatible with third-party cloud and LoRa network ecosystem partners.
At its core, it uses Laird’s field-proven RM1xx module hardware, providing LoRaWan options at 868 and 915MHz, plus BLE for local data display, configuration and troubleshooting.
It comes equipped with enclosures, multi-layer security to safeguard networks at every level and support services, and is certified for FCC, IC, CE and Bluetooth SIG listing.
