Set a threshold
Water only below a moisture level.
Step 04
Run it
Let it manage watering automatically.
Working Principle
The sensor reads soil moisture and the controller opens the water valve only when the soil dries past a set point, saving water.
The science behind it
A closer look
It's feedback control with a setpoint; watering on demand cuts waste versus a fixed timer.
