Moisture-Sensitive Irrigation System
Using a moisture sensor to control a solenoid water valve
Using a moisture sensor to control a solenoid water valve
Challenge: Make an irrigation system that opens a water valve when the soil becomes too dry and closes the valve when the soil is sufficiently watered.
