Infrared Motion Detectors
This Infrared Motion Detectors project is specifically designed and comes with a detailed
writeup on one of the numerous applications of Infrared devices. Beginners to electronics will
appreciate the construction of this project as it will teach the students of electronics how to
identify resistors colour code, identification of capacitor's value, maximum working voltage and
its tolerances as well as right soldering method. It includes schematic diagram, parts list,
printed circuit board (PCB) pattern layout and a detailed description of each section that
makes this device works.
This project describes the concept of Infrared, Operational Amplifiers concept and
applications (as comparator, low pass filter, high pass filter, band pass filter etc) and
sound generator integrated circuit which gives a ding-dong sound. This document also describes
the troubleshooting guide and a quiz to ensure that the concept
is clearly understood by the constructor.
There are many applications for the use of the detector. The most common is in the alarm system
industry. Some of the new applications are automatic door openers, light switches in hallways,
stairways and areas that increase safety for the public. Further applications can be seen in
automatic production lines, switching of sanitary facilities, monitors and intercoms. With the
ease of installation and the low suspectibility to interference from other forms of radiation,
such as heaters or windows, the Infrared motion detectors are ideal devices.
You can find the
AK510 Infrared Motion Detectors kit here
under the SURVEILLANCE AND SECURITY (SPY) category.
