Overview
Universal wireless interface for digital sensors, supporting RS-485 (Modbus), RS-232, and SDI-12 protocols.
The Geolook Digital Node (BEAM-DG) is designed to bring wireless connectivity to modern "smart" sensors. Unlike traditional analogue gauges, digital sensors process their data internally and output a digital string. This node acts as a transparent bridge, reading these complex digital signals and transmitting them via LoRa to the central gateway. It is the critical link for monitoring digital sensor chains, such as In-Place Inclinometers (IPIs) or ShapeArrays, where dozens of individual sensors are daisy-chained on a single cable. By handling protocols like Modbus RTU and SDI-12 natively, the BEAM-DG eliminates the need for cumbersome multiplexers and data loggers at the borehole head.

Detailed Description
The Digital Shift
Geotechnical monitoring is moving toward digital sensors. Why? Because in a digital sensor, the conversion from 'physical phenomenon' to 'data' happens inside the sensor itself. This eliminates signal degradation over long cables.
The BEAM-DG preserves this precision. It doesn't interpret the reading; it simply transports the exact digital value from the bottom of the borehole to your cloud dashboard with zero error.
Environmental & Industrial Protocols
Beyond structural health, the BEAM-DG is a powerhouse for environmental monitoring. It natively supports SDI-12, the standard protocol for 'smart' environmental sensors.
This allows you to easily connect multi-parameter weather stations, soil moisture probes, or water quality sondes, integrating environmental data into the same platform as your structural safety data.
Eliminating Multiplexers
Traditionally, reading multiple sensors required a complex, expensive Multiplexer (MUX) box. The BEAM-DG effectively replaces the MUX. By leveraging the addressing capabilities of Modbus and RS-485, a single compact wireless node does the job that used to require a large cabinet of switching electronics.
Mastering Sensor Chains
The most powerful application of the BEAM-DG is reading 'Sensor Chains.' In deep excavations, engineers use In-Place Inclinometers (IPIs) consisting of 20, 30, or even 50 sensors connected in a single line.
Wiring 50 analogue sensors would require a massive cable bundle. With the BEAM-DG, you connect just four wires (Power and Data). The node cycles through every address on the chain, collects the data from all 50 depth levels, and transmits it in a single packet.
Smart Power Management
Digital sensors often require more power than passive analogue gauges. The BEAM-DG features an intelligent power scheduling system.
It keeps the external sensors powered off to save battery life. When a scheduled reading is due, it wakes up, powers the 12V bus, waits for a user-defined 'Warm Up' period to ensure stable readings, collects the data, and then powers everything down again.
