Tank Topper PCB

Description

Never run out of water with the Tank Topper

This is the PCB I designed for the Tank Topper. The relay is a 12v relay and is triggered by 5v from the Arduino. 12v should be supplied to the board which also powers the Arduino Nano. The 4 pin connector on the board is designed to connect directly to the water level sensor but can be used for almost any sensor.

If you need an Arduino Nano sensor/relay breakout board, this is perfect!

Arduino Pins

• Pin 8 – Output to trigger relay
• Pin 7 – Input form sensor

Sensor Pins (4 pin JST with 2.5mm spacing)

• 1 – 5v
• 2 – Ground
• 3 – Signal
• 4 – NA
