Hi I am akash Diwate student of an engineering would like to research over pir energy conservation system. Thus I required the detail information in terms of ppt as well as PDF hence it is kind request to give it me as early as possible...

The conservation of energy states that the total amount of energy in any closed systemremains constant but can't be recreated, although it may change forms, e.g. friction turns kineticenergy into thermal energy. In thermodynamics, the first law of thermodynamics is a statement of the conservation of energy for thermodynamic systems, and is the more encompassing version of the conservation of energy. In short, the law of conservation of energy states that energy can not be created or destroyed, it can only be changed from one form to another.Energy conservation is the practice of decreasing the uantity of energy used whileachieving a similar outcome. Individuals and organi!ations that are direct consumers of energymay want to conserve energy in order to reduce energy costs and promote economic, politicaland environmental sustainability. There is provided an infrared sensor unit for deactivating an electrical appliance whenleft unattended by its user. The sensor unit includes a passive infrared sensor for sensing the user through a field of infrared light provided within a viewable distance of the electrical appliance.An ad"ustable timer is in electrical communication with the passive infrared sensor for countingtoward a predetermined amount of time when the user is not sensed within the field of infraredlight. The sensor unit further includes a controller device which is in electrical communicationwith the ad"ustable timer for deactivating the electrical appliance upon reaching the predetermined amount of time.
