Critical asset data at your fingertips
Built by RST Instruments’ 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.
RSTAR Affinity gateway
The RSTAR Affinity gateway is easy to set up and connects seamlessly to RSTAR Affinity data loggers for real-time data delivery and communication suitable for a wide range of wireless geotechnical monitoring applications and sensor types.
The RSTAR Affinity gateway receives telemetry from RSTAR Affinity data loggers and tilt sensors through LoRa radio or Smart Mesh protocol. The data is forwarded to the Terra Insights cloud server through wired internet, Wi-Fi, LTE, Sat Link, or to an on-premises server through local ISM radio. For constrained or sight-line impeded deployments, the RSTAR Affinity gateway employs the Smart Mesh protocol in a mesh topology for inbound communications from RSTAR Affinity data loggers and tilt sensors.
The RSTAR Affinity gateway enables secure wireless communication between data loggers and the Terra Insights application so sensor data can be transmitted and analyzed. The RSTAR Affinity gateway provides bi-directional connectivity between sensors in the field and Terra Insights. A pole mount is included with the gateway enclosure. An optional wall mount is also available.
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.
The RSTAR Affinity data logger is designed to connect a variety of field analog and digital sensors to the Terra Insights dashboard including Measurand’s ShapeArray. Each data logger can be field or factory configured to support up to five instruments of any type.
Instrument and data logger configuration is mediated through secure and authenticated Bluetooth (BLE).
Instrument readings are communicated to Terra Insights 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 synching of instrument data by local authenticated download in the Terra Insights mobile app.
Instrument Interface Modules (IIM) allow RSTAR Affinity data loggers to accommodate up to five different sensor types in a single node. Each of the logger’s five channels can be fitted with the appropriate module for the sensor type of your choice.
Each connected instrument has its own logging schedule. Data sample and port sample, and/or event alert threshold intervals can be globally or independently configured (between one minute and seven days) for each IIM.
Built to the customer’s specifications and configured by Terra Insights’ dashboard and/or mobile application to report logging intervals and/or alert thresholds reached based on the IIM, each data logger communicates with the closest RSTAR Affinity gateway within its range.
The set of instruments that each data logger supports is custom-configured, calibrated, and tested at our factory according to your order specifications and stores data locally to an onboard flash memory. The RSTAR Affinity data logger is powered by up to three 13 Ah primary lithium-thionyl chloride (Li-SOCl2) cells, each with its own fuel gauge.
