WIRELESS ELECTRICAL APPARATUS CONTROL SYSTEM USING IR COMMUNICATION WIRELESS ELECTRICAL.doc (Size: 54 KB / Downloads: 26) ABSTRACT: Controlling electrical appliances through IR remote is interesting and very useful application. This is a stand alone project as it can be used by physically challenged as well as old people to turn loads ON/OFF .This system is widely used in industries, offices, Banks, hotels, hospitals, and display boards. In this project, IR is used for controlling any appliance in an industry by controlling the loads. IR rays are transmitted through remote and these rays are received by a receiver named TSOP 1738. Here, in this project AT89S52 is used as a controller. The IR rays received by TSOP are given to the controller for the respective loads ON/OFF. Now, in the receiver section, the loads are controlled through triac driving circuit. In the triac driving circuit, as the controller cannot provide sufficient current and these triacs in turn are connected to loads. The uniqueness of this project is, loads can be controlled by IR signal. Using keys on remote the loads can be switched ON/OFF from remote place. This project uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac out put of secondary of 230/12V step down transformer. |
