Assembly of the thermal imaging camera
1. First place the Arduino board in the housing with the battery compartment
2. Using super glue or epoxy, fix the servo motor in the empty space in front of the Arduino.
3. Place the second servomotor into the rotary and secure the entire structure to the servomotor.
4. now, you need to connect the MLX90614 to the Arduino. To do this, connect Ground to GND, Vin to 3.3V, SDA to pin 4, and SCL to pin 5. Also, install a 4.7 kOhm resistor from SDA to 3.3V and a second one from SCL to 3.3V. See the diagram below.
5. Connect a Laser Card or laser pointer. The laser is needed so that you can see where the thermal imager is currently scanning.
6. Afterwards, mount the webcam and orient it exactly with the IR sensor and the laser so that they are pointing at the same point. This completes the assembly of the thermal imaging camera.
