RSTAR L900 Wireless Data Acquisition for Geotechnical Instruments
Производитель
RST Instruments Ltd.
Описание оборудования
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.
