as a simple solution ,you can use of photo electric sensors and install them against each other on the door frame so that as you enter the room the beam of light is cut and send a pulse to the electronic circuit to turn on the lamps and when you leave the room again send a pulse to turn of the lamps.

Several companies here in the United States (Leviton, for one) make what is called an "occupancy sensor". This device normally mounts in a standard switch box, which would of course be mounted near a door leading into the room in question. This sensor can tell when there are people in the room and will keep the lights on until the last person leaves. Depending upon the sophistication of the sensor, some have time off delays and other programmable features. Check out

for more information. There are also devices that send signals over the electrical lines that utilize "smarthome" technology, where various devices can "talk" to each other or to a central control unit - this can get as complex as you want. A good source for these devices is

they will send you a catalog with some fairly good information - the web site is informative as well.
