Infra-red movement sensor (june 1991 - nov 1991) / Norbani Ab. Rahman and Rosmazita Hussain

This project is about Passive InfraRed (FIR) sensor. It can be used to avoid our house from intruder. The device works by sensing a change in radiated heat, cause by movement of human body by the fact that human body emits infra-Red radiation. It can be devided into two parts. The Interface as a receiver and detector as an input. Interface can accept up to four detector which we can put in different places. The sensitivity is also important to make sure that it can just detect a human body.
