Development of Low-Cost Thermal Camera for Examine Human Body Temperature

Abstract

Thermogun is non-contact thermometer to examine people whom body temperature above 37°C that is used to screening human body temperature while entering public areas such as schools, offices, and supermarkets. Thermo gun is widely used yet not effective because it measuring single point around body or face which cannot represent whole body. Thus, the development of thermal camera is important. This research focusing on development of low-cost and low-resolution thermal camera to replace thermo gun. Thermal camera measure 36°C, 37°C, 38°C object temperature and gives accuracy respectively 99.38%, 99.39% 99.41%. Therma camera not only give high accuracy but also high precision. The precision for same temperature respectively 35.01 ± 0.63 when measure 36°C object temperature, 36.55 ± 0.26 when measure 37°C object temperature, and 37.27 ± 0.49 when measure 38°C object temperature. This result is satisfied and good enough to examine human body temperature.
