General discussion • Are Raspberry Pi 4 GPIO pins sufficient for motor, pump, and sensor control?

Hello,

I’m using a Raspberry Pi 4 Model B and I need to perform the following tasks for a project:

I will control a motor or a water pump, which may be 220V AC, 12V DC, or 24V DC (I haven’t decided yet). I’m looking for a safe control module that would be compatible with all three cases (e.g., a relay module or motor driver).

I also need to read data from both digital and analog sensors through GPIO,

And send output signals via GPIO pins.

So my main question is:
Are the built-in GPIO pins on the Raspberry Pi sufficient for this kind of setup, or do I need additional modules (such as an ADC converter, GPIO expander, or motor/pump control board)?

As far as I know, the Raspberry Pi doesn’t have native analog input, so I may need an ADC. If you can recommend reliable or commonly used modules for these tasks, I’d appreciate it.

I’m planning to use basic sensors like temperature, humidity, or pressure sensors, though I haven’t finalized the components yet.

Thanks in advance!
