Water Level indicator using IC https://rb.gy/1u8xnt
We generally worry about the wastage of water, when we switch ON the motor and forget to turn it off. The Water Level Indicator employs a simple mechanism to detect and indicate the water level in an overhead tank or any other water container. We have posted already a Water Level Indicator and Controller using IC ULN2003. In this article, we are presenting a very useful, cheap and simple Water Level Indicator circuit using transistors (bc547) for beginners. This circuit indicates the level of water in the water tank using LEDs with transistors. you can use this project as a college project.
Circuit Components
4 – BC547 transistors
3 – 220-ohm resistors
3 – LEDs
1 – Buzzer
5 – 9v battery + battery clip/power supply
some pieces of wire
The connections arrangements are shown in the circuit diagram shown above. The +9V power supply or battery is used. In this circuit, we have used all the transistors as a switch. The water touches the wires’ contact with base of each transistor, a small current flows through the base and turns on the transistor as the transistor turns on, the LED connected to it glows. LEDs will be turned on depending upon the level of water. We have used a buzzer with the last transistor as water touches the base of the last transistor collector the collector and emitter connected and buzzer rings. The relay can be connected instead of the buzzer to auto control the water level in the tank.

In my previous video i have made a water level indicator with in UNA2003 IC. Today I am presenting a very useful, very cheap and very simple circuit using transistors for beginners in the field of electronics. This simple circuit can indicate the level of water in your tank using LEDs as well it will alarm as tank will be full.
