The Project Report On Energy Saving Through Counter is about Energy saving through counter. Most of the energy we use today comes from coal, oil, and natural gas. They are fossil fuels. They take millions of years to form. We can’t make more quickly. They are non renewable. We need to save energy. A good way to save energy is by not wasting things. Don’t use paper plates or cups all the time. You only use them once and then throw them away. Write on both sides of your paper. Use a lunch box and thermos instead of paper bags and box drinks.
Present project 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 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 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 is electromagnetic relay.
Project Report On Energy Saving Through Counter Conclusion:
In conclusion we can say that, 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 not only counts the no. of person, it also saves the energy used by the appliances.
