Water Level Alarm Indicator Circuit Diagram!! Water Level Alarm Circuit Diagram
Today I am going to talk about a very useful project that I had taken up. It is called the Water Level Indicator. Nowadays everyone 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 comes 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.
4 - bc548
6 - 220 ohm resistors
3- color led
1 - buzzer
1 - 9v battery + battery clip
The circuit consisting of 5 sensing probes which is dipped in water to sense the level of water. The probe A is connected as common to other four, which should be at the bottom most part of the water tank, also it act as a reference level. The probes B, C, D and E are set as minimum, minimum+, middle and maximum level respectively.
When water in the tank touches the probe A and B both, a small current flows from A to B through water and to the base of transistor T1 via a 220KΩ resistor. As a result of the transistor conducts causing the LED1 to glow. Likewise, when water touches sensor C, LED2 glow and indicates that WATER is at minimum+ and when water touches sensor D, LED 3 glow and indicates that WATER is at. MIDDLE. Finally, when the water touches sensor E, BUZZER turns on and indicates the tank is completely filled.
