Comparison of Temperature Measurements by Wired and Wireless Room Temperature Sensors

In this study, a comparison of nine wireless and two conventional wired temperature sensors (all available on the market) was conducted in a climate chamber with a two-person office setup. Measurements were conducted under both radiant and all-air cooling systems, each with two levels of cooling load (33 and 61 W/m² ). Sensors were placed in a total of seven positions, varying the location and height (0.6, 1.1, 1.5 m). Each of the sensor measurements was compared with a reference air and globe temperature at the same position. Results show that conventional wired temperature sensors measured closer to globe temperature sensors rather than air temperature sensors due to their casing, while wireless sensors varied in their sensitivity to radiation due to different shapes and materials.
