Energy saving through counter



abstract

Present project and implimentation is designed using AT89S52 microcontroller to count the number of person present in the room and to save the energy used by the appliances. The project and implimentation utilizes the IL74 optocoupler which is used to detect the visitors. If a person enters in the room then optocoupler will detect the person and the buzzer will generate a sound and there will be an increment in the number of person on the LCD. LCD used in our project and implimentation is JHD162A which is used to display the number of person

ABSTRACT

Present project and implimentation is designed using AT89S52 microcontroller to count the number of person present in the room and to save the energy used by the appliances. The project and implimentation utilizes the IL74 optocoupler which is used to detect the visitors. If a person enters in the room then optocoupler will detect the person and the buzzer will generate a sound and there will be an increment in the number of person on the LCD. LCD used in our project and implimentation is JHD162A which is used to display the number of person. If a person leaves the room then optocoupler will detect the person and buzzer will generate a sound and there will be a decrement in the number of person. On the basis of number of person, different appliances like bulbs, fans, A.C., T.V. etc. can be switched on/off automatically by using relays. A relay is an electrically controllable switch. It allows the isolation of two separate sections of a system with two different voltage sources. Relay used in our project and implimentation is electromagnetic relay. When there will be no person in the room then no device will work. Devices will work only on basis of no. of person present in the room. Thus, this project and implimentation not only counts the no. of person, it also saves the energy used by the appliances.
