Water Level Indicator using BC548 Transistor (Mini Project)

Water Level Indicator Using BC548 Transistor


Components :

Total Components : 4
  • 3 Different Color of LED
  • Led - LED used to indicate the level of Water present in tank.
  • 1 Buzzer
  • Buzzer - If the water is full, buzzer will turn on hence the user can switch off the sump.
  • Battery - 9v, Battery for Power supply.
  • Transistor - BC548
  • This project uses the working principle (switching concept of Transistor).
Circuit Diagram :

Water will conduct electricity, place different length wires for different level of indications when water level goes up (touches wires) different level Indicators(LED’s) will be turned on thro’ transistors .
