Due to the COVID-19 coronavirus pandemic, you should be careful and follow the recommendations of medical services.
CoroFence, a DIY thermometer that constantly measures the body temperature of the surrounding people, can help in recognizing the symptoms of the disease.
The author of this DIY, Marius Dima, shared his design of a thermal imaging thermometer that measures the temperature of people walking past the device. The result of the measurement is sent to the database, where you can see the history of measurements and compile statistics. CoroFence also informs you of the results with an RGB LED and a buzzer that sounds when it detects temperatures above 37 degrees Celsius.
To create CoroFence, the author used an Arduino Nano 33 IoT, a motion sensor, a Panasonic Grid Eye temperature sensor, a buzzer, an RGB diode and a lithium-ion battery. All these components were placed in an electrical installation box that serves as a housing for this thermometer.
The key element of the whole project is the infrared sensor. He is responsible for measuring the temperature in his environment. This sensor has 64 independent measurement points (8 × 8 square), which makes the measurement more accurate. In order to save the battery, the author additionally used a PIR sensor, which checks on an ongoing basis whether there is a human being within CoroFence. When motion is detected, the Arduino activates the infrared sensor and measures.
