I took ECE342 in Spring 2021, and the design project of my group is making a non-contact temperature scanner. The scanner is required to show the accurate temperature, to alert the user when they have a fever, no contact to function, to log user information, be intuitive and show the temperature in Fahrenheit and Celsius. The temperature sensor I used is the MLX90614 Thermal Sensor. MLX90614 uses laser or infrared to measure the temperature of an object. Its operating voltage is 3.6V to 5V. The temperature range that can be used for detection is − 40F to 185F.
