Gentlemen, there is a Raspberry Pi, and there is a door for which you need to install an open-close sensor and write information when it is open-closed in the log.
What are the solutions?

Optocoupler, limit switch, reed switch (as mentioned above) - at least three options.

Magnet, magnet sensor, GPIO connector on raspberries. Well, most likely a couple of resistors.

Mmm, I asked the question badly, I'm more interested in specific solutions. Well, for example, a set on ebay for this, something like that.

I will be original: ultrasonic or IR distance sensor, GPIO on raspberry...
