Sentrius™ RS2xx Next-Generation LoRaWAN Temperature Sensor

Under Development: Preview


Our Sentrius™ RS2xx is a battery powered IP67 temperature sensor platform that delivers HACCP level temperature monitoring with real time alerting for your food safety compliance. In addition to ensuring product safety, these intelligent devices avoid inventory loss, improve facility efficiency and save you time and money in automated day to day operations. 

Our RS2xx sensor is available in two variants: One with an internal temperature sensor, and a second that supports an external sensor probe via a USB-C connector. 

The improved RS2xx is the outcome of real-world use and feedback from our market leading RS1xx sensor family implemented in 1,000s of restaurants, convenience stores and supermarkets globally. It builds on that QSR domain expertise, weaving in Ezurio’s decades of experience in designing wireless IoT devices. This layers in deep expertise in radio and antenna design and optimization to effect the longest wireless range, whilst always ensuring robust, reliable data integrity in the harshest of RF environments. 

The RS2xx is a small form factor device utilizing LoRaWAN for long range data transmission and Bluetooth LE for OTA configuration and troubleshooting. The device has been designed to send highly accurate temperature readings tested to the EN12830:2018 standard for temperature recorders. 

Ezurio offers full customization of the final product, including software, configurations, enclosures and labelling, to enabling you to create a truly unique branded device for your end customers.
