This is a simple project to control a fan using a Raspberry Pi and a temperature sensor.
- Raspberry Pi Pico
- USB cable
- 1x DS18B20 temperature sensor
- 1x 4.7k resistor
- 1x 12 V fan (You can use the fan you want, but you need to change the circuit to match the fan voltage)
- 1x 12 V power supply (Or the voltage of the fan you are using)
- 1x TIP41C transistor (Or any other transistor that can handle the current of your fan)
You can use one of the following options:
| Used library | Version |
|---|---|
| OneWireNg | 0.13.1 |
| DallasTemperature | 3.9.0 |
| ezButton | 1.0.4 |
| ezOutput | 1.2.0 |
Note: OneWire does not work with the Raspberry Pi Pico, so I used OneWireNg instead. The reason is described in this Github issue and in this Arduino forum.
