Hi, I am in my final year of elecrtonics at college and I need help on my project for this year. My project, as you can see in the subject box, is a motion sensor alarm.
I need some basic information on the sensors I can use. I think there are two types of sensors I can use, which are PIR (pyroelectric infrared sensor) and Passive-Optical Person sensor. Can you please give me links or basic knowledge on how these devices work. I would be very much appreciated. ...
