This document describes a simple water level indicator circuit that uses LEDs connected to different water levels as grounds to indicate the water level in a tank. When the water reaches a certain level, it connects the ground of the LED at that level, causing it to light up and show the water level without using any transistors or integrated circuits. The circuit diagram created in Proteus software shows how the LED grounds are set at different levels so each LED only turns on when the water reaches that point.
Water level indicator
- 2. Water level indicator is a mini project which tells us about the water level in the tank or glass. We can use it as high level. It can be used in home water tank to show the level of the water in the tank. Explanation:
- 3. I have used a new idea of making the water level indicator. You can find this project easily on internet in which transistor and ics are used. But I have not used any transistor and any ic. I have just used the simple concept of taking water as a ground. So when the negative of led and negative of battery is connected through the water then the led on. If the grounds of both not connected through the water then led does not on. New Idea:
- 4. Circuit Diagram on Proteus:
- 5. The grounds of different leds are set to be different so that the specific led just on when the water reaches at that point. Ground:
- 6. Working Diagram:(all the grounds have different levels)
