Shematic to conrol a Fan with the Raspberry Pi.
To build the Circut you need a 10k Pull-Down Resistor, a 1.6k Base Resistor for the Transistor, a Transistor and a Diode.
For this Setup you need:
- a RPi 4
- tmp102 Temperature Sensor
- 1x 1.6k Ohm Resistor
- 1x 10k Ohm Resistor
- 1 BC357 Transistor
- 1 Diode (I think it doesn't really matter which one, the current is very low)
- 1x 12V Fan
- 1x 12V Power Supply
You need the following Python packages:
- Flask
- GPIO for RPi
Or you can use a Docker Container with the run-contrainer.sh Script.
Configure the ports in the App.py File or inside the run-container.sh script to the ports you need for your service.
To run the Service, start App.py using python3 App.py. I recommend running this servie with Docker or nohup.
To run the Fan Control with Docker you can use the pre cooked script build-contrainer.sh. It will run the Dockerfile and create an Image for you. Then just use the pre cooked scrpit run-contrainer.sh and start it. Maybe you should lookup both scripts if you want to use different ports!
