Overengineered Irrigation
Overengineered Irrigation V: Capacitive Sensors and The Winter
Let's add some pumps to transfer water into plant pots! This will require mostly a lot of woodworking and electrical routing. Lots of pictures this time!

ReadOverengineered Irrigation III: Moisture Sensors
In order to ensure that each plant gets the right amount of water, we need to measure the moisture contents of the soil quite accurately. The easiest way to do that is to measure the voltage between two electrodes in the soil.

Some new parts arrived today (specifically 10kΩ resistors), and it's time to connect the relay module with the controller circuit!
