This document describes the design and implementation of a smart parking system using wireless sensor networks. It includes block diagrams of the transmitter and receiver sides which use IR sensors, microcontrollers, and displays. It also lists and describes the hardware modules used, including power supplies, sensors, microcontrollers, displays, and communication modules. Sample code is provided for configuring the UART, transmitting data, and initializing and writing to an LCD display. References used in the project are listed at the end.

- 5. MODULE 1: Power Supply for 8051 Microcontroller The power supply section is the important one. It should deliver constant output regulated power supply for successful working of the project. A 0-12V/1 mA transformer is used for this purpose. The primary of this transformer is connected in to main supply through on/off switch& fuse for protecting from overload and short circuit protection. The secondary is connected to the diodes to convert 12V AC to 12V DC voltage. And filtered by the capacitors, which is further regulated to +5v, by using IC 7805
- 6. MODULE 2 Sensors – IR Active (emitting) Oscillator generates IR reflections off objects Filtered receiver looks for “reflections” Pulses may be encoded for better discrimination Typically frequencies around 40KHz Doesn’t work well with dark, flat colored objects Passive (sensor only) Pyro-electric (heat sensor) Look for IR emissions from people & animals Used in security systems & motion detectors

- 8. MODULE 3 What is ARM ? ARM stands for Advanced RISC Machine. 32-bit General Purpose Micro-Processor Architecture RISC Design offering: a high instruction throughput an excellent real-time interrupt response a small, cost-effective, processor macrocell. ARM cores are widely used in mobile phones, handheld organizers, and a multitude of other everyday portable consumer devices.

More about ARM Spun out of Acorn Computers Designs the ARM range of RISC processor cores Licenses ARM core designs to semiconductor partners who fabricate and sell to their customers Also develop technologies to assist with the design-in of the ARM architecture Why is it called Advanced RISC Machine ? Because ARM has the ability to access two instruction sets 32-bit ARM instruction set 16-bit Thumb instruction set
