Abstract [en]

The main aim of my project is to develop a hardware implementation of the electronic waterheater by choosing different components and minimize the errors in the same. I have consideredseveral options depending on the availability of components, cost, reliability, implementation,financial budget, specification and thinking about the professional technical skills required. Inthis project I designed and implemented, an AVR micro controller based water temperaturemeasurement system using Atmega328p microcontroller.The idea of the project came from a company called Relek production AB, Sweden and theydevelop and supply electrical equipment for heating: such as electric boilers, under floor heatingboilers, IR heaters, emergency power plants, power monitors, etc. Now they want to develop anew version of electronic water heater and according to their specification.The microcontroller (Atmega328p) based temperature control system is used in this project forproviding better functioning of the system and will also serve the following purposes.1) As there will be less usage of energy as it is more energy efficient.2) The microcontroller along with temperature sensor decides when the heater shouldturn on/off.With this project I have designed the schematic diagram by using Eagle Autodesk PCB CADprogram. The seven-segment display is used in this project to show the current temperature. Atemperature sensor (LM35) is used in this project to sense the temperature and give thesemeasured values to the microcontroller. The temperature measurement and heater control areprocessed using C++ program.I have connected the circuit as per the schematic diagram and programed the microcontroller,interfacing all the major components like 7 segment display, temperature sensor, 2 pushbuttons(for manually incrementing and decrementing the set point in the program), and optoisolator (tosense the output from microcontroller and control the heater through thyristor).
