In This Instructable You Will Learn How To know If The Plant Wants Water Or Not.
We use the concept of checking the electric current flow in plant. The electric current varies with the level of water in the plant.
Step 1: Requirments
You Will Need Only A Few Things:
1) A Plant.
3) 350mA Adapter OR A 9v Battery.
4) Some Wires.
5) Paper Clips (As Electrodes)
6) Table Salt OR Common Salt.
Step 2: Making The Device.
We have to insert two electrodes in a plant. Insert The Electrodes In The Stem About 5cm Apart.
Step 3: Procedure
First we have to insert two electrodes in a plant. We pass 150mA in one of the electrode. At the other end the current is read. The current is automatically calculated by he ammeter/multimeter and necessary action is taken based on the reading.
Water acts as a resistance. So less the water in the plant, less the current is passed. More the water in the plant, more current is passed.
Step 4: Result
Step 5: Conclusion
This would reduce the work of humans to look after the plants and save water. It will allow the plant to grow automatically. Practically this device is very useful to humans; it does not wait for humans for any commands, but tells the human if the plant needs water or not.
