1.0 Configuring EEPROM and
testing the script |
|
1.1 |
From the command line or Terminal
window start by running the following command : |
|
pi@raspberrypi ~
$
sudo rpi-eeprom-config -e |
| |
To configure the fan to power off after
system shutdown, Add "POWER_OFF_ON_HALT=1"
at the end of the file that reads like this:
|
|
 |
|
1.2 |
Reboot your
Raspberry Pi 5 to make the change take effect. |
| |
pi@raspberrypi ~
$
sudo
reboot |
| |
|
|
1.3 |
Update your system and install the required Python
libraries: |
| |
pi@raspberrypi ~
$
sudo
apt-get update |
| |
pi@raspberrypi ~
$
sudo
apt-get upgrade -y |
| |
pi@raspberrypi ~
$
sudo apt install python3-gpiozero |
| |
|
|
1.4 |
Download the script
and enter the directories: |
|
pi@raspberrypi ~
$
sudo
git clone https://github.com/suptronics/x-fan40.git
/opt/x-fan40 |
| |
pi@raspberrypi~
$
cd /opt/x-fan40 |
| |
|
|
1.5 |
Run the script to
start CPU temperature-based fan speed control |
| |
pi@raspberrypi:/opt/x-fan40~
$
sudo
python3 fan_controller.py |
| |
|
|
1.6 |
Run the script to
monitor fan RPM |
| |
pi@raspberrypi:/opt/x-fan40~
$
sudo
python3 rpm_reading.py |
| |
|
|
2.0 Execute the fan
auto-control script at Raspberry Pi boot |
|
2.1 |
Create the service configuration
file: |
| |
pi@raspberrypi ~
$
sudo nano /etc/systemd/system/fan-controller.service |
| |
Copy and paste the following configuration: |
|
[Unit]
Description=Fan Controller
After=multi-user.target
[Service]
Type=simple
User=root
ExecStart=/usr/bin/python3 /opt/x-fan40/fan_controller.py
WorkingDirectory=/opt/x-fan40
Restart=always
RestartSec=5
StandardOutput=journal
StandardError=journal
[Install]
WantedBy=multi-user.target |
| |
|
| |
Save and exit
(Ctrl+X, then Y, then Enter). |
| |
|
|
2.2 |
Reload systemd and
Enable Service |
| |
pi@raspberrypi~
$
sudo systemctl daemon-reload |
| |
pi@raspberrypi~
$
sudo systemctl enable fan-controller.service |
| |
pi@raspberrypi~
$
sudo systemctl start fan-controller.service |
| |
|
|
2.3 |
Check if the service is running properly: |
| |
# Check service
status |
| |
pi@raspberrypi~
$
sudo systemctl status fan-controller.service |
| |
|
|
2.4 |
Reboot your Raspberry Pi to verify auto-start: |
| |
pi@raspberrypi~
$
sudo reboot |
| |
|
| |
# After reboot,
check if the service is running: |
| |
pi@raspberrypi~
$ sudo
systemctl status fan-controller.service |
| |
|
