This study integrated a RFID wireless sensor network with Decision Support System in the management of ambient temperature in the medical industry. This system uses signal detection to track and monitor changes in temperature, to enhance the convenience and efficiency of managing temperatures. This study completed the following objectives: (1) Develop an automated system to collect and record temperature-related data. In the event of an exception, management personnel are immediately notified. he proposed system helps to maintain the correct temperature and reduce labor costs. (2) Employ a decision agent to provide the most appropriate contingency measures to deal with abnormal conditions using a remote graphical interface capable of monitoring all related devices. (3) All temperature-related data is recorded to provide long-term historical records and make reports to facilitate the normal operation of thermostats.
