Design of a non-contact body temperature measurement system for smart campus

Since fever is developed in most people infected by communicable diseases, body temperature monitoring is effective for the prevention of outbreak of such diseases. Because of outbreaks of influenza in Hong Kong, some schools are required to measure the students' forehead temperature when they arrive at the school. The repetitive tasks of attendance taking and temperature logging consumes considerable amount of manpower, time and administrative resources. To facilitate such daily operations at the school entrances, an automated system with the integrated functions of attendance taking and temperature measurement is being developed in collaboration with an access control company in Hong Kong. This paper presents our prototype system, which consists of non-contact temperature sensor, embedded system, and database. Using a specialized mechanical fixture and simple calibration technique, preliminary results show desirable temperature measurement performance.
