    In the tank there is a set of sensors to be precise there are 7 sensorsin the water water. Just think them as a switch, as the work of the sensor will be to connect a circuit. I will explain in details in my instructables. So the water starts to get filled in the tank and when the water level in the tank starts to rise up, what happens is that the sensors that is installed in the tank starts to get activated one by one indicating the water pdf in the tank.

    And finally when it reaches to its top font sensor, there will be a visual display as well as a sound from the unit indicating that the water has filled in the tank and one can be alerted that the tank has been filled up and the water pump has to be switched off saving the electricity bill as well as over flow of water from the tank.

    The Circuit It has numerous transistors acting as a switch and the switch gets activated when the sensors tell them to. The heart of the circuit is the transistors BC There are total7 transistors in the circuit and each one will be sensing the level of water present in the overhead water tank. Firstly when you power the unit it will be monitoring the power present in the unit and secondly it is also the indicator telling you that there is no water at level present in the tank.

    As because the water level is below the No. Therefore when you switch on your unit if you see only one Red LED lighting up then you know that the is no water present in the tank and gerritszoon you should make you water pump on. The Buzzer Part Here you can add any of the normal buzzers that are readily available in the market and if it is not then you can make yourself with a simple IC. I am giving a small circuit diagram, it is really simple to make and there are minimum parts.

    It file a simple audio oscillator. I have also provide a circuit diagram here but if you are able to manage a buzzer then no need to assemble this circuit. The Power Supply This section contains a transformer converting the mains voltage V bring down to 9V. There is a bridge rectifier containing 4 diodes and making the Alternating current to Direct Current. After the filtering the voltage is then directly fed to the voltage regulator with a filtering capacitor.

    From the regulator IC the output voltage is then again filtered with a capacitor and is fed to the circuit. This comprises the power supply of the device.
