Week 12 (FYP2) : Troubleshooting

Hi, this week, i will be discuss about troubleshooting. Troubleshooting is a very important step, before you can present your project to your assessors. this is to prevent further humiliating, if the project not working.

For my project, i had found 1 problem, and it was related to PIR sensors. Upon investigation, the problem was because of the range of detection for the both PIR sensor. It was known that PIR sensor has long and wide detection range, so range of detection for both PIR sensors, overlapped with each other. To solve this problem, I used a cardboard, and cover the PIR sensors. This is to limit their range of detection.
 

Figure above shown the range of detection for PIR sensor.
