We are extending the temperature controller that we have built in the course of last three guides. We'll extend the main circuit built on Perma-Proto HAT to provide three male jumper pins that will be connected with the optical sensor breakout board.

1 x Water level sensor
Infrared water level sensor with breakout board

We'll be using this optical water level sensor breakout board from dfrobot that simplifies the integration of optical sensor with GPIO pins of Raspberry Pi

1 x ATO Water pump
Water pump to pour RO/DI water from ATO container to reef tank
1 x Power adapter
