Water Level Indicator and Alarm System
- 1. Water Level Indicator By: Asad Ahmed Khan Muhammad Ali
- 5. 1 k ohm Resistor.
- 8. Transformer.
- 9. LEDs.
- 11. Bridge Rectifier: Bridge Rectifier is actually a bridge of Diodes 1N4007.This is used to convert 12 V AC (coming from Transformer) to 12 V DC which is supplied to circuit. LEDs: Light Emitting Diodes, Placed in circuit, to show level of water in Tank. These diodes are operated at 1.5 V 470 ohm Resistors: 470 ohm Resistors are installed in the circuit because LED is Operated at 1.5 V, and we are having 4.7 V there, so in order to decrease the voltage across LED we placed 470 ohm resistors
- 15. Can be used to measure underground storage of water.
