Pot Water Level Indicator

Hi,

I am rafeeq and my partner poornima from white field nook.

Today we are showing how to do pot water level indicator.

Step:1

Materials:

• Wires
• Coin cell
• Coin shield
• Transistor
• Resistor
• Mud
• Plant
• Led
• Paper cups
• Switch
• Water

Step:2

• Take a transistor,resistor and led.
• Connect transistor, led and connect resistor on bottom led and transistor.
• And connect wires to transistor,resistor as shown in the figure.

Step:3

• Connect coin shield and switch to the transistor and led.
• Take a cup of mud and keep the connected transistor,led and wires to it
• And plant the small plant to the cup.
• And put some water to the plant.
• When we on the switch the led on . when we keep the wire in the water the led not on because water is a conductor.
• Now the pot water level indicator.
