Water level indicator project for school science exhibition. The level of water in overhead water tank can be measured using this LED indicator. according to the water level detected, water level is indicated as 'Low', 'Medium' and 'High'. When tank water level is full then the alarm is sounded alerting the user to prevent overflow of water. The project is done using NPN transistors, LEDs, resistors and Buzzer.
