A Bash-based installer for a Python-powered fan controller on Raspberry Pi, designed for Debian-based systems (e.g. Raspberry Pi OS). It sets up a systemd service to automatically manage your fan based on CPU temperature.

- Installs a lightweight Python script to control a GPIO-connected fan

- Automatically starts the fan controller using systemd

- Monitors CPU temperature and toggles fan based on thresholds

- Logs installation output to `/var/log/pi_fancontroller.log`

- Includes a clean uninstall option

- Raspberry Pi running a Debian-based OS (e.g. Raspberry Pi OS)

- GPIO-connected fan (default GPIO pin: 17)

**NOTE: Do NOT connect the fan directly to the GPIO pins, a transistor circuit must be used**

- Python 3 installed

- `gpiozero` Python library (installed automatically if missing)

- Must be run as root (use `sudo`)

Make new file on your Raspberry Pi:

*nano pi_fancontrol.sh*

Copy and paste the contents of:

into the new file.

Make the file execuutable:

*sudo chmod +x pi_fancontrol.sh*

Run the installer:

*sudo ./pi_fancontrol.sh*

The script contains an uninstaller. To run it use --uninstall:

*sudo pi_fancontrol.sh --uninstall*
