How do you make a water level indicator project?
Get all of the supplies that you need first such as LEDs, a buzzer, and sensing wires. Then build the circuit and attach the battery. Watch the LEDs light up as the water level rises and listen for the buzzer when the level gets too high!
What is water level indicator circuit?
A water level indicator is an electronic circuit which indicates the various levels of water inside a tank. This happens when rising or dropping water levels come in contact with the respective water sensors arranged step wise inside the water tank at different depths.

How does a simple water level indicator work?
The working principle of a water level indicator is actually quite simple. Water level indicators work by using sensor probes to indicate water levels in a storage tank. These probes send information back to the control panel to trigger an alarm or indicator.
Which transistor is used in water level indicator?
BC 547 Transistor
Water Level Indicator Using BC 547 Transistor.
What are the applications of water level indicator?
Applications & Uses Of Water Level Indicator
- Can be used in water tanks to control water levels.
- Automatically turn ON/OFF pumps.
- Can be used in factories, commercial complexes, apartments, home,
- Fuel tank level gauging.
- Oil tank level control.
- High & low-level alarms.
- Pool water level control.
- Life station switches.
Why BC547 transistor is used in water level indicator?
Whenever tank gets filled, we get alerts on particular levels. The LEDs is generally used for indicate the water levels. If the water level is full, then the circuits beeps through the buzzer notifying that the water level is full.
Why BC547 transistor is used?
BC547 is usually used for current amplifier, quick switching and pulse-width modulation (PWM). Therefore, if you need to control the speed of a motor or actuator in some of your projects, you can simply use this transistor to achieve it.
What is the objective of water level indicator?
Purpose of Water Level Indicator The purpose of a water level indicator is to gauge and manage water levels in a water tank. The control panel can also be programmed to automatically turn on a water pump once levels get too low and refill the water back to the adequate level.
What is the function of water level indicator in boiler?
The function of a water level indicator is to indicate the level of water in the boiler constantly. It is also called water gauge. It helps the operator in keeping the level constant from outside through a glass tube. In case of need, if the level falls down, water will be pumped by the operator.
How does a BC547 transistor work?
The BC547 is a NPN transistor meaning when power is applied to the base (control pin) it will flow from the collector to the emitter. Typically NPN transistors are used to “switch ground” on a device, meaning, they are placed after the load in a circuit.
What is the function of transistor in water level indicator?
Principle: The water level indicator circuit consists of a transistor element and a buzzer which indicates the overflow of water or excessive water in the container. When the water reaches to maximum limit it shows and blinks the LED with buzzer sound to stop pouring or filling water.
What is the conclusion of water level indicator?
Conclusion. The water level indicator is the best electronic starter device indicating the water level and saves water correspondingly. The led blinks according to their level of water reaches to them and indicates the buzzing sound to stop pouring when it reaches its final limit.
How many level indicators are there in water level indicator of a boiler?
Two water level indicators
1. How many level indicators are there in the water level indicator of a boiler? Explanation: The function of the water level indicator is to indicate the level of water inside the boiler drum at any given instant. Two water level indicators (one as a standby) are fitted at the front of the boiler drum.
Which type of transistor is BC547?
Bipolar Junction Transistor
BC547 is a Bipolar Junction Transistor, abbreviated as BJT. It is an NPN transistor. It has three terminals named as: Emitter.
What is the operating voltage of water level sensor?

What does BC mean in BC547 transistor?
B- stands for Silicon Transistor C for- Audio Frequency Range.
Why are two water level indicators used in a boiler?
Water Level Indicator: It helps the operator in keeping the level constant from outside through a glass tube. In case of need, if the level falls down, water will be pumped by the operator. According to IBR, each boiler should be essentially fitted with two water gauges. Figure 3.9 shows the water level indicator.
What is the function of economizer?
Economizers are heat exchangers that transfer the heat in the flue gas to another medium‚ generally the boiler feed-water‚ although other streams are sometimes used such as make-up water.
What does B indicate in transistor BC547?
The semiconductor device like a transistor is one kind of switch which controls electrically. It consists of three terminals like an i/p, o/p & a control line. These are named as the emitter (E), collector(C) and base (B).
What is the output of water sensor?
Water Level Sensor Pinout It is recommended to power the sensor with between 3.3V – 5V. Please note that the analog output will vary depending on what voltage is provided for the sensor. – (GND) is a ground connection.
