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).
