Water Level in the Plants

In This Instructable You Will Learn How To know If The Plant Wants Water Or Not.

• We usually give water to the plants by pouring water in the soil. In this way water is absorbed by the soil. è we do not know that whether the plant want’s water or not. Water may be poured in the soil but we do not know whether this water is required by the plant? In that case it is wasting precious resource like water. In some circumstances water in the plant gets vaporized due to the heat and plant needs water for its metabolism and water is not available to plant as we follow our pattern of watering plant.

We use the concept of checking the electric current flow in plant. The electric current varies with the level of water in the plant.

This device tells us how much water is actually there in the plant. This conserves upto 90% water, and prevents it from being wasted. If used in society, this precious resource(water), can be saved a lot.

You Will Need Only A Few Things:

1) A Plant.

2) Voltmeter.

3) Power source (Try to use less voltage like 1 V or 2 V).

4) Some Wires.

5) Paper Clips (As Electrodes)

6) Hot glue / candle wax .

First:

We have to insert two electrodes in a plant. Insert The Electrodes In The Stem About 5cm Apart.

First we have to insert two electrodes in a plant. We pass electricity in one of the electrode. At the other end the current is read. The current is automatically calculated by the voltmeter/ multi-meter and necessary action is taken based on the reading.

Water acts as a resistance and it is not present in pure form but in form of a solution. So less the water in the plant, less the current is passed. More the water in the plant, more current is passed.

• If The reading Is Less Than The Original reading On The Voltmeter Then The Plant Needs Water.
  
• If The reading Is More Than The Original reading On The Ammeter Than The Plant Does Not Need Water.

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.
