Water Level indicator with alaram

Circuit Diagram with detail tinyurl.com/2uhsmzjw
Water Level Indicator using IC tinyurl.com/water-level-indic...
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.
Water tank level control
Automatically turn ON/OFF water pumps
It is used in factories, commercial complexes, apartments, home,
Fuel tank level indicator
Oil tank level control and indicator
High & low-level alarms
Pool water level control
Leach-ate level control
Cooling tower water level control
Sewage pump level control
Remote monitoring liquid
Pump controller Auto
Stream level monitoring auto
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.

[@arnoldtraviezo5601]

Hello. Good project. Two questións: How long the sensor cables must be to get the device functioning properly? Could it be 10 meters (30 feet), for example? . (Note: when I say "sensor" I mean the cables which are in contact with the water). By the way, I suggest to add a switch on/off to turn off the circuit when it is not working. This way the battery would last a lot more. Thanks, friend, and keep on projecting.
