During the COVID-19 crisis, it can be valuable to know if you, or persons close to you, have a fever or not. Having a fever can be one of the symptoms of being infected with the Corona virus. So I came up with designing a device around a far infrared Thermal Sensor, a Raspberry Pi and a small TFT display. The face skin temperature of a healthy human being is in the range of 32 to 34 degrees. Skin temperatures higher than that might indicate a fever. Since the package is small, it is easy to place it e.g. next to a door entrance.
