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

Power Tool Proposal – Task 3 In order to operate at maximum profit levels‚ a business must have lower operational costs than the competition. The means to satisfying lower operational costs is Supply Chain Management. Supply Chain Management is a cross-industry wide philosophy to improve operational efficiency by integrating activities of obtaining goods and services to create a product. When implementing a supply chain strategy‚ consideration must be given to the approach given to suppliers

Why use regulated power supplies? The ideal voltage-regulated power supply would have the following features: 1. Zero output impedance at DC and at all frequencies 2. Zero regulation (constant DC output voltage) for a wide range of AC line voltages and over the entire range of load currents that are required by the powered circuitry. 3. Zero power dissipation. 4. Instantaneous recover from changes in line voltage and load current. 5. Overload protection so that normal operation is automatically
