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 1: Wires

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 2:

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.
