Smart Contactless IR Thermometer using Arduino and Android Circuit Diagram
The working principle is very simple, the infrared thermometer sensor MLX90614 reads the human body temperature when the distance ( measured by IR sensor ) between the forehead and the sensor matches a set value. After making the circuit, I realized that the wiring connection is really messy. To make the wiring cleaner and simpler, I have
3D Printed Enclosure for Contactless IR Thermometer. The idea of the project is to make the thermometer compact enough to mount it along with our phone. We designed a CAD model to fit all the electronics into a neat little box used paper clip to secure the device with the phone. The CAD model is shown below.
DIY Non Contact IR Thermometer V1.0 Circuit Diagram
To operate the IR thermometer, you need to continuously press the longest button (the one we soldered to pin D5 of the arduino), bring the thermometer close to an obstacle and when the thermometer is close enough, it will beep and take the temperature. You can change the mode (medical or object) by pressing the other button for about 3s.
