Experimental setup:

Figure 2: Experimental Setup

Taking Arduino pro mini as an example, the experimental setup is mainly composed of the following parts: Arduino board is responsible for running the code and connecting other components, Thermopile sensor (MLX90614) for temperature detection, and OLED screen (SSD1306) displays the temperature reading in real time. In addition, USB to TTL is to connect the computer and Arduino board to upload the code. The λ650nm red LED helps us visually locate the direction and position of temperature detection, and the 9V battery ensures that the detection setup can carry out on-site testing.
