xfreelifex WROTE:how to attach this project with my webcam so i can record any motion detect??
A webcam needs computer for interfacing.
Basically you'll need to connect this PR project set to your computer (usually is using UART and you'll need to modify the source code), then write a program to run on your computer to read the UART data from PR project set and command the webcam to snap photo when motion is detected.
Anyway, there're many ways to connect the sensor to computer. Another way would be using the PIR sensor (without PR project board) and a USB to UART converter (UC00A). In this case, no embedded programming is needed but you need to detect the signal from the sensor through UC00A. A sample of using UC00A with computer program for this purpose is given here:
