Parts needed

This page does not list all resistors or small components. It only shows the main components.

• Solar panel e.g. 30W
• cheap solar charger
• 12V battery with enough capacity to support the ESP32 and it's senors and the pumps
• Any ESP32 development board
• 12v submerge pump
• waterproof housing
• electrical parts, like resistors, voltage regulators, MOSFET's, ...

Here is my PCB for demonstration purpose only. Your setup might look different depending if you want buttons or OneWire Sensors.

Minimum needed:

• The 12V Voltage regulator
• At least one MOSFET or relais for the pump
