Our design challenge was to create a contactless temperature sensor capable of accurately measuring, storing, and displaying human temperatures. The purpose of the design was to create a tool capable of screening people for fevers, an early indicator of infection, with a minimized risk of spreading infection. To accomplish this we used a thermopile, which can remotely determine a person’s temperature by measuring the thermal infrared radiation all heated objects naturally emit. We also built a system capable of scanning personal identifier barcodes, storing test data in an external database, running on computer or battery power, displaying temperature results on a seven-segment display, and alerting users to fevers using a speaker. Some things we did very well. We successfully designed a prototype that is very compact and light, which is useful for transporting and setting up in various locations. We also successfully used a thermopile to contactlessly measure user temperatures. However, other parts of the design leave room for improvement. Although we can clearly see the thermopile measurements vary with temperature, we didn’t manage to calibrate the device to a high level of accuracy. We also didn’t include a way to power off the system, leading to problems with battery life and charging.
