RSTAR Affinity Data Logger
The RSTAR Affinity data logger is a multi-sensor digital node that connects to different types of instruments with the innovative quick connect cable or conventional cable glands. Offering unprecedented modularity, scalability and flexibility, the RSTAR Affinity data logger is designed to be durable, quick to set up and versatile enough for any geotechnical monitoring application.
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.
RSTAR Affinity
Built by our team of seasoned instrumentation experts specifically for geotechnical monitoring projects, the RSTAR Affinity system comprises loggers, gateways, secure communications for data telemetry, and mobile and desktop applications. Forget the headaches of improvised monitoring solutions cobbled together from different third-party vendors. RSTAR Affinity represents your complete industrial internet of things (IIoT) solution for reliable, real-time data flow from your work site to your desktop—all from a single source.

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!
