Connect a 9V battery to the circuit. Regulator IC 7805 provides regulated 5V output to run the circuit. Note that you can also use a 12V DC power supply depending on your motor pump. During testing at EFY Lab, a 12V DC supply was used for the water motor pump.
To test the project, insert the sensor probe into the soil. Switch on the power supply to the circuit. If the soil is dry, the motor will automatically turn on and the LCD will show ‘Dry soil, Motor on’ message.

You can further extend this project to make a practical drip irrigation system. Typically, a drip irrigation system requires some special components and control systems. For example, you may need distribution lines (both large- and small-diameter pipes and pipe fittings), electronic or hydraulic control valves, poly fittings and accessories (to make connections), emitters, drippers or spray heads depending on the design and application.
