, Introduction.
Water level indicator is widely used in many industries and houses. People generally worry
about the wastage of water, when they switch ON the motor and forget to OFF them. A Water
level indicator may be defined as a system by which we can get the information of any water
reservoir. Water level indicator system are quite useful to reduce the wastage of water from any
reservoir, while filling such reservoir. But for domestic purpose we cannot go for the instruments
which use radar or ultrasonic principle that costs high. Water tank overflow is a common
problem which leads to the wastage of water. In this project using the transistor based water level
indicator circuit is very useful to indicate the water levels in a tank. Whenever tank gets filled,
we get alerts on particular levels. The LEDs is generally used to indicate the water levels. If the
water level is full, then the circuits beeps through the buzzer notifying that the water level is full.
The circuit is designed to indicate three levels of water stored in the tank: low but not empty, half
and full but not overflowing. When there is no water in the tank, all the LEDs are off as an
indication that the tank is completely empty. When water level increases and touches the sensor,
the Red LED will glow indicating that there is water within the tank. As the water level
continues to rise and reaches half the tank, Yellow LED will glow. When the water in the tank
rises to full an alarm is made by the buzzer as an indication that the tank is full.
In this project I will be building a water level indicator using four BC547 transistors with three
levels that consist of inside a tank with the help of 3 LED and a buzzer to indicate that the tank is
full.
