When the water level reaches to Point A in the tank, the positive side of the battery gets connected to the base of the Transistor Q1 through the water.You can see resistors (R1, R2, R3) at the base of each transistor, which is used to limit the maximum Base current.
How does a water level indicator circuit work?
When water level increases and touches the sensor, the Red LED will glow indicating that there is water within the tank. As the water level continues to rise and reaches half the tank, Yellow LED will glow. When the water in the tank rises to full an alarm is made by the buzzer as an indication that the tank is full.
What are the components of water level indicator?
Required Components for Water Level Indicator
- 555 timer IC.
- Buzzer.
- Resistors (22K Ohm – 1, 570 Ohm – 1, 1K Ohm – 2)
- Capacitors (1 uF 1)
- Breadboard.
- Connecting wires.
- Battery with Battery Snap Connector.
Which sensor is used in water level indicator?
A magnetic float sensor is a device used to detect the level of liquid within a tank. The switch may be used in a pump, an indicator, an alarm, or other devices. Magnetic float sensor is an electromagnetic ON/OFF switch. It helps to sense the level of water present in the overhead tank or sump.
Why bc547 transistor is used in water level indicator?
Water tank overflow is a common problem which leads to the wastage of water. In this project I am using the transistor based water level indicator circuit is very useful to indicate the water levels in a tank.If the water level is full, then the circuits beeps through the buzzer notifying that the water level is full.
How do you use a plant water level indicator?
It can display the water level to remind you of watering. – When there is no water in the pot, the buoy of the water level gauge will be at the bottom. On this note, pull up the water level and water plants through the hole. – Simply insert the level into the soil, and it will help your plants grow healthy and strong.
How do you make a low water level indicator?
Test the water level indicator.
Slowly fill up the glass, cup, or container with water. Watch as the LED with the longest wire indicates when the water level is lowest and how as the water level rises, the LED with the shortest wire shows when the water is at the highest point.
What does a water sensor do?
Water sensors detect the presence of water and, when placed in locations where water should not be present, a leak.Some water-sensor systems can be programmed to shut off the water to the house to help prevent a small leak from becoming a large one.
Can ultrasonic sensor detect water level?
With ultrasonic sensors, we can find the water depth calculation by finding the distance between the transceiver and the surface of the water. The sensor will transmit a short ultrasonic pulse, and we can measure the travel time of that pulse (the echo) to the liquid and back.
Who invented water level indicator?
Mr. Markose is 30 years of age and has studied upto the 9th standard. He is working on daily wages as a Lascar in Kerala Samuhya Jalasechana Samithi. He has invented new device called “Water Level Indicator” to monitor water level in wells.
Can I use BC548 instead of BC547?
NO, BC547 is an NPN and BC548 is a PNP transistor both the transistors are not substitute to each other.
What is the use of BC547?
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 function of BC547 transistor?
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 a hydroculture plant?
Hydroponics means the cultivation of plants in water rather than soil. These plants are widely used in offices and other business premises because hydroponic care is so easy.
When were hydroponics invented?
In the late 1920s and early 1930s, Dr. William F. Gericke of the University of California extended his laboratory experiments and work on plant nutrition to practical crops growing outside for large scale commercial applications. In doing so he termed these Nutriculture systems hydroponics.
What is simple water level indicator?
Simple Water Level Indicator.When water is rising the base of each transistor gets electrical connection to 6V AC through water and the corresponding probe. This, in turn, makes the transistors conduct to glow LED and indicate the level of water.
What is water level indicator project?
The Water Level Indicator employs a simple mechanism to detect and indicate the water level in an overhead tank or any other water container.Most water level indicators are equipped to indicate and detect only a single level.
How is water level measured?
Electric water level meters referred to as sounders are frequently used in groundwater to measure level. These instruments are essentially tape measures with a probe on the end. Once the sensor contacts the water, it completes a circuit, causing an indicator to beep and an LED to glow.
Why is proximity sensor used?
A proximity sensor is a device that can detect or sense the approach or presence of nearby objects and for this it does not need physical contact. There are different kinds of proximity sensors. Some of them are listed [8]: Inductive: This type of sensor is used to detect nearby metallic objects.
What are the different types of level sensors?
7 Main Types of Level Sensing Methods How do they differ?
- 7 Main Types of Level Sensing Methods – How do they differ?
- Optical Level Switches.
- Capacitance.
- Ultrasonic.
- Microwave/Radar.
- Vibrating or Tuning Fork.
- Conductivity or Resistance.
- Float Switch.
How do smart water detectors work?
Smart water sensors can help you detect a leak before it causes damage.When water (or high humidity, or a risk for freezing pipes) occurs, sensors set off a physical alarm or trigger an alert to be sent via WiFi to your phone or computer. Some systems can even automatically shut off valves to prevent major damage.
