ABSTRACT
This project presents how we use the sensors and electronics circuit for residential and household purpose.
Here in this project we show that how we use conductive sensor to control the working of pump. Working of the pump is controlled by the water level of the source tank, if the main tank is empty then pump gets automatically on and when it is fully filled then pump’s get automatically off. But even when there is no water in the source tank, pump will remain switched off. So working of the pump totally depends upon both, the source as well as main tank.
CHAPTER 1:-
Introduction
1.1 AIM:
The main aim of Automatic water level monitoring and control is:
We know that the demand of electricity is very high than demand in our country so, Automatic water level monitoring and control is to save electricity.
To save water which is the First necessity of human being
To Increase pump set life.
To protect motor from getting damaged in case of no load (i.e., no water in main line condition), because in industries where large pumps are required for water intake, there the motor protection is necessary.
1.2 LEARNING OBJECTIVES
Development on MIC-89C52: This contains an automatic movement that can save water from overflow.
Implementation of important subjects of engineering studies such as Embedded Systems, Control Systems, and Machines etc. to the fullest.
1.3 MOTIVATION:
Water level controllers Indicator is highly recommended for metro cities or areas where drinking water is supplied through pipelines which are further distributed in homes, hotels, societies etc. At large these systems not only help us but our neighborhoods and society also, as it reduces the wastage of water by cutting down any further overflows than what you need. This system can also help in saving the electrical energy by making automatic switching of electrical motor when there is no water in main pipeline or when water overflows.
1.4 OVERVIEW:
This product is designed to automatic control of motor, which ensures constant reserve of water in storage tanks. Automatic water level controller is used to automatically fill the over head tank as and when it gets empty and monitor the water level in it.
Automatic water level controller switches ON the motor when the water level in the overhead tank drops below pre fixed low level(on point) and puts off the motor when water level rises up to pre fixed high level (off point) motor also switches off when the sump water is exhausted before filling overhead tank, pump running dry, Mains voltage fluctuations.
CHAPTER 2-
Theoretical background
Why we are choosing a Microcontroller?
As it provides on chip microprocessor, RAM, ROM, Parallel I/O port, Serial I/O port etc. hence its cost is less, size is less, power consumption is less and speed is more.
Software development tools like assembler, C compilers etc are easily available and are easy to upgrade
History of the Microcontroller
Introduction
A microcontroller (also MCU or µC) is a computer on a chip. It is a type of microprocessor emphasizing high integration, low power consumption, self-sufficiency and cost-effectiveness, in contrast to a general-purpose microprocessor (the kind used in a PC). In addition to the usual arithmetic and logic elements of a general purpose microprocessor, the microcontroller typically integrates additional elements such as read-write memory for data storage, read-only memory, such as flash for code storage, EEPROM for permanent data storage, peripheral devices, and input/output interfaces. At clock speeds of as little as a few MHz or even lower, microcontrollers often operate at very low speed compared to modern day microprocessors, but this is adequate for typical applications. They consume relatively little power (milliwatts), and will generally have the ability to sleep while waiting for an interesting peripheral event such as a button press to wake them up again to do something. Power consumption while sleeping may be just nanowatts, making them ideal for low power and long lasting battery applications.
Microcontrollers are frequently used in automatically controlled products and devices, such as automobile engine control systems, remote controls, office machines, appliances, power tools, and toys. By reducing the size, cost, and power consumption compared to a design using a separate microprocessor, memory, and input/output devices, microcontrollers make it economical to electronically control many more processes.
