Abstract
Abstract In the post-epidemic era, for quickly and accurately screening people with abnormal body temperature in small crowds and providing efficient methods for epidemic control, a multi-functional identification thermometer was designed and produced. The device uses the Raspberry PI GIS camera to accurately locate the face and identify the identity information of the measured person. The device uses the AMG8833 infrared array thermal sensor for infrared temperature measurement and the HC-SR04 ultrasonic ranging module for temperature compensation. Through multiple temperature compensation experiments, the measurement error is maintained between ±0.2°C. Based on the mathematical model of temperature compensation, the device can match the identity of people with abnormal body temperature through the database. The research results show that the device is of great significance for improving the efficiency of epidemic prevention and management cost control.
