Abstract
Nowadays, human has become too busy and he is unable to find time even to operate the lights and fans wherever not necessary. This can be seen more effectively in the case of lights in the rooms. This project gives the best solution for electrical power wastage. Also the manual operation is completely eliminated.
The Project Automatic auditorium control system using Microcontroller is an interesting project which uses AT89S52 microcontroller as its brain. This system switches on the lights only in darkness.PIR sensor is used for the movement reorganization. This is a simple, fit and forget system. If some movement is identified in the auditorium the light will automatically switched on else it will be off.
To operate the fans automatically, temperature has to be read continuously. For this, Thermistor is used. Thermistor reads the temperature value continuously and gives this value to the ADC. ADC0804 is used to convert analog data delivered by Light dependant Resistor (LDR) into digital data. This ADC interfacing makes this project highly sensitive and user friendly. LCD is used to display the related messages.
