Drip irrigation, also known as trickle irrigation or micro irrigation or localized irrigation, is an irrigation method that saves water and fertilizer by allowing water to drip slowly to the roots of plants, either onto the soil surface or directly onto the root zone, through a network of valves,pipes, tubing, and emitters. It is done through narrow tubes that deliver water directly to the base of the plant.

Step 1: Materials Required

main items:

1. pipes //choose two different sizes of pipe as u require.
2. pump
3. power supply ,( can be battery,adapter...)
4. switch for on and off

tools:

• cutter
• screwdriver
• tape

making it automatic just require a microcontroller

• i have used arduino mega 2560

Step 2: Making Stand

cutting the long pipe in small one as shown in the pic above

Step 3: Making Hole in the Stand for Small Pipe

making a hole in the pipe so that small pipe can be inserted and fixed into the ground.

Step 4: Connection

make the hole in the long pipe and connect it to small pipe..

Step 5: Pump

close the other end of the pipe..

you just need to connect a pump to the end of the pipe and connect it to a power source................

this is only for manual process

Step 6: Making It Automatic

for this you require a micro controller

and an 5v pump or u can purchase 12v and add a relay..

upload the code to arduino and see the comments of the code for connections

details of making it automatic is written in the code itself.......
