Planet Arduino

In the age of COVID-19, being able to know when someone’s sick is vital, especially in countries where the disease is currently surging. It’s for this reason that Open Green Energy decided to build a battery-powered portable thermometer that not only takes a person’s temperature but also alerts other if it’s too high.

At the heart of the device is an Arduino Nano that takes in temperature data from a GY-906 module and displays it on a 0.96” OLED screen. Additionally, there’s an IR emitter/receiver that detects when a person is in front of the thermometer so their temperature can be read. If the value falls within the acceptable range, a green LED lights up, but if the value is too high, such as in the case of a fever, a buzzer begins to sound, and the red LED turns on. 

All of the electronics were assembled onto a custom-designed PCB that has headers for the various modules and LEDs, along with a place for the Arduino and battery charging circuit. All of these components were then positioned inside of a 3D-printed enclosure that holds both the batteries and PCB at the bottom and the screen/LEDs at the top.

If you want to measure the temperature of an object, one very convenient way is to use an infrared thermometer. MN Maker didn’t have one, and after wondering just how hot a component was getting, he decided to simply build one.

His device utilizes an Arduino Nano for control, and resides inside a 3D-printed enclosure that he designed. Temperature sensing is handled by an MLX90614 IR thermometer on a GY-906 breakout board, and a small laser is used for aiming. Once the temperature is obtained, it’s displayed on an OLED screen in the back of the housing in both Celsius and Fahrenheit. 

Arduino code and print files are available via the project’s write-up.
