Noise Level: 25 dB 3 dBCode ExamplesExample 1: Python Script to Control the FanThis example demonstrates how to control the fan using a Python script on the Raspberry Pi 4.```
import RPi.GPIO as GPIO
import time# Set up GPIO mode
GPIO.setmode(GPIO.BCM)# Define the fan pin
fan_pin = 17# Set up the fan pin as an output
GPIO.setup(fan_pin, GPIO.OUT)try:
while True:
# Turn the fan on
GPIO.output(fan_pin, GPIO.HIGH)
time.sleep(5)
# Turn the fan off
GPIO.output(fan_pin, GPIO.LOW)
time.sleep(5)
except KeyboardInterrupt:
GPIO.cleanup()
```Example 2: Systemd Service to Run the Fan at BootThis example demonstrates how to create a systemd service to run the fan at boot on the Raspberry Pi 4.Create a file `/etc/systemd/system/raspberrypi-fan.service` with the following contents:
```
[Unit]
Description=Raspberry Pi Fan Service
After=multi-user.target[Service]
ExecStart=/usr/bin/python /home/pi/fan_control.py
Restart=always[Install]
WantedBy=multi-user.target
```
Create a file `/home/pi/fan_control.py` with the following contents:
```
import RPi.GPIO as GPIO# Set up GPIO mode
GPIO.setmode(GPIO.BCM)# Define the fan pin
fan_pin = 17# Set up the fan pin as an output
GPIO.setup(fan_pin, GPIO.OUT)# Turn the fan on
GPIO.output(fan_pin, GPIO.HIGH)while True:
time.sleep(1)
```
Enable and start the service:
```
sudo systemctl enable raspberrypi-fan.service
sudo systemctl start raspberrypi-fan.service
```
Example 3: Bash Script to Monitor Temperature and Control the FanThis example demonstrates how to create a bash script to monitor the temperature of the Raspberry Pi 4 and control the fan accordingly.Create a file `/home/pi/temp_monitor.sh` with the following contents:
```
#!/bin/bashwhile true
do
temp=$(vcgencmd measure_temp | egrep -o '[0-9.]+')
if [ $temp -gt 55 ]
then
echo "Fan on"
gpio write 17 1
else
echo "Fan off"
gpio write 17 0
fi
sleep 5
done
```
Make the script executable and add it to the cron job to run at boot:
```
chmod +x /home/pi/temp_monitor.sh
sudo crontab -e
```
Add the following line to the cron job:
```
@reboot /home/pi/temp_monitor.sh
```NotesMake sure to install the necessary dependencies, such as RPi.GPIO, before running the examples.
Ensure proper wiring of the fan to the Raspberry Pi 4 GPIO pins.
Modify the code examples as needed to suit your specific use case.I hope this documentation helps you get started with the Raspberry Pi 4 Case With FAN - Model H4!
