Today I am going to talk about a very useful project that I had taken up. It is called the Water Level Indicator. Nowadays everybody has overhead tank at their homes. But everyone who has a water tank above knows the kind of problems that they face. Firstly there is no system to track the water in the tank. Then there come a secondary problem that is when their water pump is started they have no idea when it gets filled up and sometimes there are situation where the pump keeps on pumping water to the tank and the water starts spilling out from the tank. There is wastage of energy as well as wastage of water.
This project that i had taken up is the result of long hours of research of work at the Internet as well as long hours of thinking. I had made various versions of the projects earlier but at last i came up with this final product. I bet this has been tested and i can now firmly say that the model would work flawlessly without any complains for years. I am saying this as i have installed this models to various houses in my neighborhood and all are working fine without any maintenance. And indeed this model is admired by all who uses it.
The house where I live in has an overhead tank which is about 30 feet from the ground level. I was getting bored going up the rooftop to check whether the tank has filled or the water level was below to start the pump. I had to do this again and again. Then I sought for a solution. I always used to think of the possibilities of how can this problem be tackled in an electronic way. After years of research and by trial and error, I found one and wanted to put whatever I have done out here so that it may be helpful to someone who has a overhead water tank at their homes.
Step 1: The Working Principle
There are Four parts in this project:-
(i) The Sensor Part
It is generally a fixed support inside the tank having some nuts and bolt with wires coming out.
(ii) The Circuit Part
It comprises the brain of the module, where in all the various inputs from the sensors are fed. It is the unit from where you will get all the information of how much of water is in the tank.
(iii) The Power Supply
It is the part where in you will be converting the A/C voltage to a regulated voltage of 5V to the Circuit.
(IV) The Buzzer Part
It is responsible for bringing up the sound when the water level fills up in the tank. It will also be having a speaker or a buzzer to alert.
