Microcontroller Based Home Security A PROJECT REPORT ON “MICROCONTROLLER BASED HOME SECURITY SYSTEM” ABSTRACT Engineering is not only a theoretical study but it is a implementation of all we study for creating something new and making things more easy and useful through practical study. It is an art which can be gained with systematic study‚ observation and practice. In the college curriculum we usually get the theoretical knowledge of industries‚ and a little bit of implementation knowledge

Objective: Verify Maximum power transfer by obtaining the Thevenin equivalent resistance (RTh) for the given voltage. Introduction: One of the main uses of Thevenin’s theorem is the replacement of a large part of a circuit‚ often a complicated and uninteresting part‚ by a very simple equivalent. The new simpler circuit enables us to make rapid calculations of the voltage‚ current‚ and power which the original circuit is able to deliver to a load. It also helps us to choose the best value

Para Quinone Dioxime (PQD) What is PQD? PQD is a non-sulphur vulcanizing agent for synthetic elastomers. It is used extensively for rapid curing of butyl stocks requiring heat resistance. Butyl of this type is used to fabricate high voltage wire and cable products‚ moulded electric components‚ and heat resistant seals and hose. PQD has also been used as part of the curative system for liquid butyl elastomers. These compounds are formulated as coatings‚ sealants and electrical encapsulants. The
