you could also use i2c for a few meters usually, and repeaters are also possible.
Anyway, it's not a problem directly on the pi. You could use ttl or usb sensors but I don't recommend usb because of latency. So I don't have a great solution since the pi has only one hardware serial port. The pi4 has more uart.
