# Analog water meter reading with line sensor on Raspberry Pi

## Hardware

- Water sensor (any model with a rotating disk with different infrared reflection should do)
- Raspberry Pi Zero W with pre-soldered GPIO pins (any RPi will do)
- Line sensor (at least with digital out, prefereably also analog out to ease debugging. Working on 3.3V or 5.0V, I used https://www.hackerstore.nl/Artikel/26)
- Jumper cables to connect to RPi (easier than soldering)
- Adruino or oscilloscope (optional but recommended to ease electronic debugging)
- Some metal/wood/putty/screws for sensor mounting
