RSTAR Affinity Data Logger
The RSTAR Affinity data logger is designed to connect a variety of field analog and digital sensors to the RSTAR Affinity web-based dashboard.
Overview
The RSTAR Affinity data logger is designed to connect a variety of field analog and digital sensors to the RSTAR Affinity web-based dashboard. Each data logger can be configured to support up to five instruments of varying types.
Instrument and data logger configuration is mediated through secure and authenticated Bluetooth (BLE).
Instrument readings are communicated in real-time by low-power wide area network (LPWAN) through an RSTAR Affinity gateway. LPWAN protocols supported include LoRaWAN for long-range outdoor applications (up to 15 km).
Standalone data logging is supported by the synching of instrument data by local authenticated download in the RSTAR Affinity Field app.

Speak with an Expert
I’m very happy with the quality of the instrumentation and technical support from RST, as always. They worked with us from the initial stages of the project to ensure that we were fully prepared and equipped to use the RSTAR network for the first time. They delivered everything within the tight project time frame to ensure that there were no delays on site, and the submersible tilt meters looked like new even after over twelve months of being submerged in Thames water!
