How do you make a water level indicator circuit?
How do you make a water level indicator circuit?
Connect the 9-volt battery to the water level indicator. Press the hexagon terminal of the battery connector onto the circular terminal of the battery and vice versa. Make sure that the battery connector is securely attached to the battery. Now that the battery is connected, your water level indicator is able to work!
Why BC547 transistor is used in water level indicator?
This indicates that the container is full. BC 547 is known as cheap and easy to use transistor which can be used to design a low-cost water level indicator. You can use this device in day to day life to detect the various levels in water in a container.
Which transistor is used in water level indicator?
BC547 transistor
1. Insert BC547 transistor on the breadboard. The left one is collector, the middle one is base and the last one is the emitter.
How does a water level indicator circuit work?
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. As mentioned above, the control panel can be programmed to automatically turn on your pump to refill the water again.
What are the components used in water level indicator?

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.
Can we use BC547 instead of BC548?
BC547 and BC548 are basically the same, but BC547 has more breakdown voltage, while BC548 features low noise. They are the most general-purpose NPN silicon transistors, and switching one to the other will not significantly affect the circuit.
What are the components of water level indicator?
What is the use of resistor in water level indicator?
You can see resistors (R1, R2, R3) at the base of each transistor, which is used to limit the maximum Base current.
How do you make an automatic water level controller circuit?
To make this circuit you will need
- BC 547 Transistor X 3 = 9 INR.
- 220 K Ohm & 5.4 K Ohm resistors = 1.
- 1N4007 Diode = 1.
- 12V relay = 12.
- One, 3-pin PCD connector & two, 2-Pin PCB connector = 25.
- Wires = 5.
- PCB = 12.
How many pins are there in the water level sensor?
3 pins
The water level sensor is super easy to use and only has 3 pins to connect. S (Signal) pin is an analog output that will be connected to one of the analog inputs on your Arduino. + (VCC) pin supplies power for the sensor. It is recommended to power the sensor with between 3.3V – 5V.
