The operation of water level controller works upon the fact that water conducts electricity. So water Water Level Indicator is a simple low cost circuit. First we. water due to overflow in overhead tanks. 'Automatic Water. Level Indicator and Controller' can be a solution to it. The operation of water level controller works. IJSRD - International Journal for Scientific Research & Development| Vol. 5, Issue 01, | ISSN (online): Automatic Water Level Indicator using .

Sai Teja2 R. There are situations where the pump keeps on pumping water to the tank and the water starts spilling out from the tank. There is wastage of energy as well as wastage of water. To overcome this problem we came up with a solution Automatic water level indicator which indicates the water levels at various levels through LEDs using microcontroller.

Sensor This article explains you how to detect and control the water A float switch is a device used to sense the level of liquid level in an overhead tank or any other container.

This within a tank, it may actuate a pump, an indicator, an alarm, system monitors the water level of the tank and or other device. Using this system, we only on DC. But, here we are designing the circuit which is used to detect and control the water level automatically in overhead tank using PV89V51RD2 microcontroller can avoid the overflow of the water.

We have already seen how wireless water level indicator which works. Automatic water pump controller is a series of functions to control the Automatic Water Pump Controller Fig.

The water level Comparator circuit: Here we are using LM sensor is made with a metal plate mounted on the reservoir comparator. LM is a 14pin IC consisting of four or water tank, with a sensor in the short to create the top independent operational amplifiers op-amps compensated level and a detection sensor for detecting long again made in a single package.

Op-amps are high gain electronic for the lower level and ground lines connected to the bottom voltage amplifier with differential input and, usually, a of reservoirs or reservoir.

The output voltage is many times higher than the voltage difference between input terminals II.

These op-amps are operated by single power 1 Sensors supply LM and need for a dual supply is eliminated. LCD The basic block diagram of the Implementation of automatic LCD Liquid Crystal Display screen is an electronic display water level indicator using microcontroller and bidirectional module and find a wide range of applications.

A 16x2 LCD visiting counter is shown in the figure below. These modules are preferred All rights reserved by www. The G.

A 16x2 LCD means it can display 16 characters per Here our microcontroller is not able to supply line and there are 2 such lines. In this LCD each character is current required for the working of a relay. The maximum displayed in 5x7 pixel matrix. For example, main function, variable Flash and bytes of data RAM. They are tank. The whole design flow chart is shown i.

Direct visual inspection system. When the water is ii. Micro-controlling inspection system. Direct Visual Inspection System tank which is continuously detected by an Liquid level gauges are designed for relatively ultrasonic sensor and displayed into a LCD straightforward level regulation and usually provide display.

When the level reached ultimate direct indications through visual, magnetic, or limit then microcontroller switched off the transduction properties. They typically consist of a measuring chamber connected to the vessel being pump. After that while discharging the monitored, with gage levels matching the changing water at certain minimum level levels in the vessel[1].

There are a variety of microcontroller switched on the pump. It different liquid level gage designs and each one also stored the time of motor of pump being features distinct operational characteristics and kept on.

A floating device equipped with a permanent magnet is suspended upon the fluid in the chamber and it moves an indicator or a transducer through magnetic coupling to produce a level reading. The design differences between these types of liquid level gages determines their effectiveness in various applications, as well as the operating parameters for individual gage units[1].

Micro-controlling Inspection System There are numerous types of level detection devices that incorporate transducers, transmitters, sensors, or indicator instrumentation to monitor and regulate industrial systems.

Most level gages rely on the principles of pressure differentials, conductivity, or capacitance and their operations can involve a range of different techniques, such as optical, electromagnetic, microwave, and ultrasonic detection methods[1].

An automatic water level indicator detects the water level in the tank.

Construction of Automatic Water Level Controller for Both Overhead and Underground Tanks

This automatic water level indicator is made up of microcontroller where programming is burnt into an IC called AT mega 8 with 32 pins. The level measurement consist of determining the distance from the bottom surface of the liquid in a reservoir or vessel up to the surface of the liquid. The detection is done by using deferent types of sensor.

Methodology At the first stage of design a water level Figure 1. Flow chart for the project sensor is been made for sensing water level accurately. Microcontroller is used to control the overall system automatically that reduces the design and control complexity. Hardware Development and Construction At first the suitable programs are developed and then the programs are simulated by using Proteus software to check whether the programs were valid or not.

Validation and correction of the simulation is really necessary. Then the circuit board is made along with the microcontroller.

The circuit is checked by using LED lights whether it works perfectly or not. After accomplishing the hardware it is associated with the water level sensor.

As it is a demo project and replicate the alternator by giving power to the system from a direct source. Now water level sensor is connected from the circuit board. Then the system is given operating condition and signal when the water level is in different position Figure 2. Block diagram of the project 4.

Circuit Diagram In figure 3 the circuit is connected to a power supply of 6 volt DC. Sonar trig pin is connected with PB0 and sonar echo pin is connected with PB1 pin.

To control over the voltage of relay driver a diode is used. Relay is connected with a motor of V.

Figure 3. Performance Test and Discussion After design And construction the system was tested whether all the connection and whole circuit was working properly or not. The system was assembled with breadboard. To ensure the proper functioning of the components Digital millimeters DMM was used. A connection of 6 volt is given. Initially the level of water was cm which was between cm to cm.

Which was indicated in display and the condition was also indicated as 'stable' as shown in Figure 6. Setting upper level of water following figure 7. The condition of motor pump was also indicated figure While reaching the upper level i.

Figure 7. Indication of water level at cm Figure 8.Used for household purposes. Using this system, we only on DC. It also provides automatic control of pumps at a remote location.

Hence, values of input voltage can be chosen such that the output is either completely off, or completely on. Battery Cap 6.
