ABSTRACT:

In today's world, a digital world indeed, use of technology is very advanced and we prefer things to be done automatically without any human efforts. This Research helps to reduce human efforts with the increase in standard of living, there is a sense of urgency for developing circuits that would ease the complexity of life. In this paper an automatic hall light control with visitor counter system circuit was designed and constructed. This research depends on the lighting system among the three power plans for green house buildings. it can be used for auditoriums, halls, shopping malls, rooms and others. Every electronic device comprises of three(3) units input, signal processor and output, in this research microcontroller (ATmega 328), lighting system, alphanumeric LCD, IR Sensor (transmitter and receiver) are used as the units. The system counts both people entering and leaving an auditorium, hall, or other location. A break in the sensor allows the system to detect the entry and exit of visitors and a successful implementation of the system will display the number of visitors in the auditorium or room. The microcontroller gives command signals to a relay driver which turns the relays such that the lamp turns ON and OFF. When the person's count is greater > 1 the lamp will turn ON automatically, but when the persons' count is zero, lamp will turn OFF automatically. Complexity of life will surely be simple if more of this is implemented.
