As an assignment for IInd semester for the session 2010-11.
To design and implement a Water Level Indicator, using
Electronic devices like LEDs, ICs, Transistors, etc.
The reason behind taking this problem into consideration was
there occurs a huge wastage of water due to overflow in overhead tanks.
Approach to Problem Solution:
Our main requirements for the indicator are as follows: o Low Power consumption o Compact, with less Electronic complexity o Simplified result o Economical So the recommended solutions for the above mentioned
o Usage of LEDs enables low battery consumption and
o Multiple LEDs give a simplified result by indicating the
level of water in the overhead tank.
o Use of a single IC to perform the computation makes it less
The 4066 chip is a Quad Bilateral Switch that can be used with digital or analog signals.
It’s a plastic version of a standard NPN Transistor and is used for small signal general purpose amplification.
SPST Switch (Single Pole, Single Throw)
A Simple on-off switch: The two terminals are either connected together or disconnected from each other. An example is a light switch.
High performance Buzzers used for indoor operations, and are moisture resistant.
LED (Light Emitting Diode)
Low cost semiconductor light source, which works on the principle of Electroluminescence.
This is the circuit diagram of a simple corrosion free water level indicator for home and industries. In fact the level of any conductive non corrosive liquids can be...
