5. Setup Instructions

5.1. Thermal Camera HAT (with 40PIN GPIO Header)

This version is designed for direct connection to Raspberry Pi boards.

  1. Direct Connection: For Raspberry Pi Zero, align the 40PIN female header of the Thermal Camera HAT with the GPIO pins on the Raspberry Pi Zero and gently press to connect.
  2. Extended Connection: For Raspberry Pi 4B or similar models, you can directly connect the HAT to the GPIO pins. Alternatively, for more flexible placement, connect the camera module to the Raspberry Pi 5 using the FPC cable. Ensure the FPC cable is securely inserted into both the camera module and the Raspberry Pi's FPC connector.

6. Operating Instructions

Once the module is physically connected and the necessary software is installed, you can begin operating the thermal camera.

  1. Power On: Ensure your host device (Raspberry Pi, PC, or Android phone) is powered on. The thermal camera module draws power from the host device.
  2. Launch Software: Open the dedicated thermal imaging software or application on your host device.
  3. View Thermal Feed: The software should display a real-time thermal video stream. Adjust settings such as color palettes, temperature scales, and measurement points as needed within the software.
  4. Capture Data: Use the software's functions to capture still images or record video streams of the thermal data.

For detailed software-specific operating instructions, refer to the documentation provided with the waveshare software or the online resources.

7. Application Scenarios

The waveshare Thermal Imaging Camera Module is versatile and can be applied in various fields:

  • Smart Air Conditioner Thermal Imaging: Monitor temperature distribution for energy efficiency.
