RFID Based Embedded System for Automatic Identity and Body Temperature Screening in the Working Environment

Monitoring human body temperature is an important aspect that plays a crucial role in maintaining a safe, healthy, and productive working environment. This paper presents an RFID based embedded system for recording the identity and body temperature of people in an industrial or institutional working environment. A prototype is developed and demonstrated using a commercial RFID tag attached to the person and a temperature screening module connected to the RFID reader. When a person with a tag enters the hotspot zone of the reader, the identity part will be automatically recorded, and the temperature sensor is facilitated in such a way that the infrared waves will hit the forehead or forearm of the individual. An ultrasonic sensor with distance logic is used to maintain the accuracy of body temperature measurements and prevent the misreading of ambient temperature as body temperature. The RSSI feature of an RFID tag is used to eliminate the ambiguity in mapping between the identity of a person and his body temperature. The acquired data from the module is transferred to the Thingspeak IoT platform to enable remote monitoring of body temperature. It is observed that the proposed RFID-based embedded system is a costeffective, non-contact, and remote monitoring solution to enhance the safety of people in the working environment.
