This project introduces a low-cost, portable device called S.C.O.T.T. that measures Mean Radiant Temperature (MRT); a key factor in understanding how hot it feels to people in an environment. The device uses several sensors to measure air temperature, surface temperature, globe temperature, and wind speed. It collects this data in real time and sends it wirelessly to be saved and analyzed.

S.C.O.T.T. was tested both in the lab and in real-world settings, including outdoor areas in Santa Ana, California, where cool pavement materials were being used. The results showed that the device could accurately detect temperature differences between areas with and without cooling treatments.

Thanks to its portability and wireless features, S.C.O.T.T. is easy to deploy and useful for ongoing research on thermal comfort, urban heat, and climate-friendly design. This tool helps researchers and city planners better understand and manage heat in outdoor spaces, making cities more livable and resilient.
