What is this?

A platform for displaying IOT telemetry on a physical gauge.

The above 12" wall gauge and the smaller 3” desktop gauge below are examples of physical gauges that display data from the U.S. Geological Survey (USGS) and the National Oceanic and Atmospheric Administration (NOAA).  These gauges show real time data from IOT telemetry collected by government maintained sensors located in the various rivers of the US. 

 

The gauges inside the wood cases are battery powered and can run 12 to 18 months on 3 AAA batteries.  The gauge face can be customized to display data from a wide variety of sources ranging from river levels to the solar powered generated by a home solar system. 

 

How It Works

A WallGauge system consist of a Gauge Data Transmitter (GDT) and a WallGauge (battery powered analog gauge).

 

The GDT beams gauge data to an infrared receiver in a battery powered WallGauge.  It connects to the Internet over your wireless network to download gauge data and converts it to a format for transmission to a WallGauge.  The GDT is a kit designed to work with a Raspberry Pi Zero WH.  This kit consist of a printed circuit board (GDT-PCB) and software (provided on a SD card).  A monthly software maintenance subscription is also required for each GDT.  For more information please see our GDT details page.

A WallGauge is a round printed circuit board housing an analog gauge (small stepper motor), infrared receiver, and a very unique processor called the Propeller from Parallax.  Firmware on the Propeller listens for commands from the GDT and will move the needle to a physical location as instructed.  This firmware is designed to work with a gauge app running on the GDT giving us the ability to support multiple gauge types. Each gauge type can have a unique gauge face and calibration table.  This unique combination of the firmware and gauge apps makes the WallGauge system highly customizable. 

If you would like to create a custom gauge we will be happy to assist as needed.  Please contact us to setup a demo and discuss your project.
