Attach a temperature sensor tag to the worker's helmet to monitor the temperature and check the temperature trends!

We would like to introduce a case study utilizing RFID tag-type temperature loggers for a demonstration experiment aimed at understanding the temperature fluctuations of workers at the job site. At Haruna Construction Co., Ltd., a general construction company primarily focused on the construction and civil engineering industries, a system for continuously monitoring the ambient temperature of workers was implemented. A demonstration experiment was conducted to determine whether it is possible to detect early signs of heatstroke risk and effectively utilize this information for safety management. By examining the temperature data over approximately two months, we were able to visualize changes in the work environment that cannot be captured by outdoor temperature alone (such as differences in work locations, the effects of direct sunlight, and the presence or absence of air conditioning). 【Case Overview】 ■ Period: April 9, 2025 – June 5, 2025 (approximately 2 months) ■ Location: Haruna Construction Co., Ltd. (Kobe City, Hyogo Prefecture) ■ Participants: 2 on-site workers ■ Equipment Used: Temperature sensor tag AXZON AZN5200 ■ Temperature logging interval: 20 minutes ＼Product catalog available for distribution/ For more details, please view the PDF data from "Catalog Download."

basic information

【Customer Feedback (Partial)】 ■ I felt that this system is attractive because it can be built at a low cost compared to existing large-scale monitoring systems and is easy to implement in small to medium-sized sites. ■ Since it allows for the visualization and individual management of heatstroke risks for each worker, I believe it can significantly contribute to enhancing overall safety management at the site. ■ Regarding the operational methods, I felt that continuous verification is necessary to consider appropriate operational forms that reflect the actual conditions of the site. *For more details, please download the PDF or feel free to contact us.
