vanwaltDataHub

vanwaltDataHub is more than a groundwater telemetry system. Designed and developed in-house and manufactured by Van Walt in the UK. Most importantly it is a self-powered, flexible system of electronics, conveniently packaged in an IP rated, heavy duty aluminium enclosure. The vanwaltDataHub performs as a data-logger so collects data from environmental and other sensors. Because it organises the data for distribution or sharing through on-board memory, radio frequency, GPRS or Satellite portals it is extremely flexible. Each unit has multiple inputs and simultaneous inputs including SDI12, Modbus, Pulse, Analog, Relay and Digital. With robust data redundancy, power independence and an internal, non-volatile memory it is a powerful data collection and distribution tool.

Advantages

The vanwaltDataHub has multiple, simultaneous inputs and outputs to connect to a wider range of environmental sensors so that data can trigger alarms; switches; other sensors and gauges. It can work in remote locations as a data-logger or telemetry system for distributing or sharing data through on-board memory, radio frequency, GPRS or Satellite portals.

Self-powered, flexible system of electronics / circuitboard
Conveniently packaged in an IP rated, heavy duty aluminium enclosure which performs as a hub to collect data from environmental and other sensors
Data is organised for distribution or sharing through on-board memory, radio frequency, GPRS or satellite portals
Modbus, SDI-12, Analog and digital I/O are provided to connect sensors singly or in daisy chain
The vanwaltDataHub modem instructs, powers, interrogates and collects data from onsite sensors
Data is stored on non-volatile memory and backed up for redundancy on an internal flash and SD card and for convenience by an external, vandal-resistant industrial grade SD card
