HARDWARE REQUIRED

SPECIFICATIONS

Power supply – 9V( from the 9v battery)

PIN DESCRIPTION

Led

BC547 TRANSISTOR

CIRCUIT DESCRIPTION

Connect the Components according to the given diagram above.

  • Connect the Components according to the given diagram above.
  • First TRANSISTOR BC547 collector connect with 330-ohm resistor to positive rail on the breadboard
  • Emitter connects to the positive terminal of led and negative terminal of led connects to the negative rail on breadboard
  • Base wire connects to the water tank

First, connect all the wire and components then connect the battery. Must use plastic glass for this project.

  • Second TRANSISTOR BC547 collector connect with 330-ohm resistor to positive rail on breadboard
  • Emitter connects to positive terminal of led and negative terminal of led connects to the negative rail on breadboard
  • Base wire connects to the water tank
  • Third TRANSISTOR BC547 collector connect with 330 ohm resistor to positive rail on breadboard
  • Emitter connects to positive terminal of led and negative terminal of led connects to the negative rail on breadboard
  • Base wire connects to the water tank
  • Positive wire from the positive rail on the breadboard connects with the water level.
  • Attach the buzzer on the breadboard.
  • Connect the positive terminal of the buzzer to the collector pin of the fourth transistor and the negative terminal of the buzzer to the GND rail of the breadboard.
  • Connect the emitter pin of forth Transistor to the positive rail on the breadboard.

  • Then connect the battery.

WORKING

When the water level reaches to point A circuit with green led & Transistor Q1 gets completed and green led glows.

Similarly when water level reaches to point B , Circuit with yellow led and transistor Q2 gets completed and yellow led glows.

Same goes with point C and finally when tank gets full at point D circuit with buzzer gets completed and buzzer starts beeping.
