In our August newsletter, we featured the meteoblue city climate monitoring system. Subsequently, our partner, meteoblue, conducted extensive summer testing of ten DL-BLG | Black Globe Temperature Sensor for LoRaWAN from Decentlab and has recently released a comprehensive report on their findings.

The Black Globe Temperature Sensorsmeasure the mean radiant temperature that reflects the apparent temperature of human bodies, which is the perceived temperature that people experience, considering the influence of shading effects from trees or buildings. 

Initial tests compared two locations: one in a park and one on a street. The first results indicate high differences between shaded (green line) and non-shaded (black line) locations and underline the importance of planting trees and ensuring enough shaded areas in cities. The mean radiant temperatures of the sensor on the sunny footwalk reached up to 49°C. In contrast, the shaded footwalk on the other side of the street reached a maximum 36°C in the analysed time period.

This information is vital for urban planning to enhance human comfort. The project will use these findings for future steps.
