WGBT Project
Dr. Michael Robinson PhD CAT(C) ATC
About
This project has three main goals:
1) Collect longitudinal data regarding WGBT temperatures.
2) Validate the accurate of a single WGBT station for a geographical area.
3) Validate an inexpensive WBGT meter against the validated reference standard.
Technical Specifications
A weather resistant housing was build to hold the unit overnight and during rain. The track is built using a barn door mounting rail and is moved using a high torque motor and conveyor belt style cable.
The motor is controlled using an Arduino One board, micro limit switches and a rain sensor. A real time clock module is also used to ensure accurate scheduling of the motor.
An Extech HT30 Heat Stress Meter is used as the validated reference standard. Data is collected using a RS-232 to USB interface by a Raspberry Pi single board computer. A basic web camera with a UV filter is used to capture images of the sky which is delivered alongside the data from the meter.
