PIR Motion sensor : http://www.sparkfun.com/products/8630
Microcontroller : A million choices. If you want Opensource, development /
prototyping : http://www.arduino.cc/
RS485 : IC : http://www0.fh-trier.de/~berres/Datenbl%E4tter/TEXAS/75176.pdf
RS232/RS485 converter : Lots available in Chennai.
BTW This is more of an hardware project than a software one.

Arun
