AIM:
The main aim of the project is to conserve the energy for corporate computers and lighting system. The project is designed especially for the people who are busy enough to even switch off their electrical appliances. The project became an eco-friendly project by conserving the energy.
PURPOSE:
Energy conservation is the practice of decreasing the quantity of energy used while achieving a similar outcome. Individuals and organizations that are direct consumers of energy may want to conserve energy in order to reduce energy costs and promote economic, political and environmental sustainability.
DESCRIPTION:
Every system is automated in order to face new challenges in the present day situation. Automated systems have less manual operations, so that the flexibility, reliabilities are high and accurate. Hence every field prefers automated control systems. Especially in the field of electronics automated systems are doing better performance.
In this project, the input is sensor is passive infra red sensor. The project ‘PIR BASED ENERGY CONSERVATION SYSTEM FOR CORPORATE COMPUTERS AND LIGHTING SYSTEM’ it consists of ATMEL 89S52 Microcontroller, relays, driver circuits, passive infrared sensor and power supply. In our project main aim is to sense the infrared radiations emitted from the body. The infrared rays can be sensed by a Passive Infra red sensor. Then signal is given to the Micro-controller. The Micro-controller activates the relay circuit. At the relay circuit, we can connect whatever the electrical equipments we want to operate like fans, computers, light etc., without using any switches. If human body is not presented automatically switch off all applications.
