About this project


It seems that writer Dean R. Koontz was right and Coronavirus pandemic is spreading at high speed.

Using airports method, scan your home visitors body temperature as soon as they ring the bell using IR remote temperature. If body temperature is normal ring the bell, otherwise an alarm will appear.

IR thermometer theory

Everything that has mass emits energy in the form of heat. Since there is heat being emitted by any object or person, an infrared thermometer can use the difference between the IR rays coming off of the person and the surrounding environment to determine temperature of the person itself.

The IR thermometer works by focusing light that is coming from the object in the form of IR rays and funneling that light into a thermopile. In the thermopile IR radiation is turned into heat, which is then turned to electricity, which is then measured.

Project details

The entire process starts with a doorbell button pressed. At that point, a hidden IR thermometer measures body temperature, the temperature is displayed in the 7 segment display screen and compared with standard fever temperatures. If visitor body has no temperature, the doorbell will ring, otherwise an alarm will alert you about a potentially infected visitor.

Coronavirus and fever

Coronavirus infected people have fever and fever can be easily measured but you have to consider that there are asymptomatic infected people and incubation periods.
