Black Globe

Build guide for a globe temperature sensor used to estimate radiant heat exposure and WBGT.

How the Sensor Works

The Black Globe temperature sensor in the 3D-PAWS system uses the high-precision MCP9808 digital temperature sensor to measure globe temperature—a critical factor in calculating Wet Bulb Globe Temperature (WBGT) for heat stress assessment. Housed inside a matte black sphere, this sensor captures the combined effects of ambient air temperature, solar radiation, and wind. The resulting data enables accurate WBGT calculations, which are essential for evaluating heat stress risk in outdoor environments. This information supports public health and safety initiatives by providing reliable, real-time monitoring for robust environmental assessment.

The Black Globe can be installed in lieu of the light sensor.
