Ever thought about creating your own home control system that can be accessed through a cell phone or a web page on your home computer? How about being able to click a button and have your Raspberry Pi play a sound file or an MP3? It's all possible using the real world examples provided in this book.

This Design Reference covers basic and advanced methods of creating embedded web pages with real-life example code. The end product will be a virtual control panel with dynamic operations that will update on the page without reloading the page simulating a real life physical control panel.  A Raspberry Pi will serve as the embedded target; however, the same concepts used here can be applied to any Linux system running the Apache HTTP Server or even Windows systems running the IIS Web Server with a few setup and path changes. This is also true of VxWorks systems when the web server is configured to use CGI, for individuals developing on an RTOS system.

Passive Infrared Motion Detector Design

Motion detectors are one of the most popular devices used in security systems today. Most motion detectors use passive sensors that can detect infrared radiation emitted by the human body. The actual motion sensor is a silicon based part that uses ceramic plates to since variations of spectral light around the 7 - 14 micrometer range.

There are many applications for passive motion sensors today including but not limited to motion sensing lighting, security systems, museum displays with automatic voice recordings, and much more. This book explains how motions sensors work, describes the use of  Fresnel lenses, and provides several motion sensing electronic designs that support a great number of sensors available on the market today.
