RaspberryPI CPU fan tuner with a s8050 triode.

This project enables a daemon which manage a CPU fan for you, it will start after system bootstrapping automatically.It enables CPU fan while its temperature is more than 45°(or defined by you), else the fan will be turned off.

You can also view your cpu temperature within this project or turn on/off a given GPIO port by simple commandline tool.

Hardware

• A Fan that works under 5v Voltage
• A NPN triode(such as s8050)

Software

• Python 2.6+
• Raspbian(optional)

At first , follow the diagram below and connect your triode and fan together.

Your triode may be like this one:

The circuit diagram is like this one:

About Raspberry Pi PIN number

Use gpio readall to get map like following image.

Enter console of your Raspberry Pi then start with

git clone https://github.com/winkidney/PIFanTuner.git

Or just download the zip file zipped by Github.

Then enter the project directory:

sudo python setup.py install

Now use following command to run fan-control daemon:

➜  ~ pi-fan-tuner fan simple --debug
DEBUG:root:Temperature 45.084 CPU fan on.

With raspbian or any system works well with systemd, you can use systemd service script to make pi-fan-tuner a daemon which automatically manage your fan.

After installation of the python package, you could run

./install-systemd-file.sh

to setup the systemd script for pi-fan-tuner.

Monitoring CPU temperature

pi-fan-tuner cpu-show --loop

For other usage, please run:

pi-fan-tuner --help
