RSTAR L900 Wireless Data Acquisition for Geotechnical Instruments
The RSTAR Array Radio Series uses wireless technology to provide automated data acquisition.
Overview
The RSTAR Array Radio Series uses wireless technology to provide automated data acquisition. A complete RSTAR L900 System uses L900 RSTAR Nodes at the sensor level, deployed in a star topology from a continuously active L900 RSTAR Hub, which consists of an L900 RTU interfaced to a FlexDAQ Data Logger. The RSTAR Array Radio Series is based on the 900 MHZ, 868 MHz, and 2.4 GHz spread spectrum band (country dependent) with extensive open-country range through use of simple dipole or directional antennae.
Power requirements for a single RSTAR L900 node is one lithium standard cell. The FlexDAQ can be powered by a solar panel, batteries, or AC power.

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!
