Design and Implement a Wireless Temperature Monitoring System using Noncontact IR Sensor Based on Arduino

COVID-19 and its genetic mutations pose a challenge to the world and affect the economic system of countries. Recently, countries were forced to reduce restrictions on airports, universities and schools. The main challenge is how to detect its symptoms without contact to the person who may have infection at local area. This depends on measuring the body temperature which represents the first and the most common symptom that can be identifies the infected people with virus or one of its strains. This paper presents an implementation of smart, and inexpensive human body temperature detector by using portable electric system based on Arduino UNO, and MLX 90614 IR temperature sensor. The measured temperature is sent to the control unit by wireless system through Bluetooth (HM-10 module) for the person walk near the IR sensor, and display it instantaneously on (16x 2) LCD. High temperature detection activates alert buzzer while a notification message sends to overseer within ten-meter distance to give a voice command asking the person to move to the safe area. The results are compared with conventional device and determined the average error between them, where the results proved the effectiveness of the proposed system in detecting the person who have high temperature without contact to that person. Where the system is operated effectively and satisfies the requirements for non-contact due to its high reliability, fast response time, and low consuming energy
