How Do you walk past a Infered Motion Detecter In a narrow hall?

step one: put suction cups on the bottom of your shoes\nstep two: walk up the wall and suction your way along the ceiling upside down\nMission Impossible Style\n\nOR\n\nPut mirrors a foot or two away from the infared light to reflect it back to the sensor and walk on the other side of the mirror and wall safely \n\nOR\n\nIf the sensors are low to the ground or all in a straight line and you have access to both ends of the hallway\nplace a supportive structure at both ends and run a ladder from one end to the other and shimmy or crawl across carefully to safety...\n\nOR\n\ndig a tunnel under the building\n\nOR\n\nrun quickly as it taked like an hour for the security company to contact the client and and the alert the police and respond - movies lie- steal a car, break in , be quick about it, grab the loot, and drive away slowly, ditch the car and dont truct anybody!

did you mean how does a light sensor work?

well for my physics project for the boards i made a photoelectronic burglar alarm- at the heart of this was an LDR( Light Dependent Resistor) when the beam of light is obstructed (think laser in the movies-lol) the LDR resistance rises and the circuit inside is set into oscillation and the alarm sounds- other good projects would be a rain alarm, a rectifier, an electroscope,..... the possiblities are endless- i suppose you could do anything involving electric circuits since thats what the cbse calss 12 physics text covers most- i doubt ud want to do anything on ray or wave optics

There should be a hallway to your left as you get outside.  It has doors at either end of it.  One has armor, and the other has a bunch of bad guys.  Get the armor first.

my answer is not pricice but may help you>\nyou need 1- mic   2- miliampir-meter  ( or AVO-meter)\nput on mA position . connect microphone tow wire to the AVO-miter \ntalk now you'll see AVO-miter pointer moves or digilat nunber increes

when you pass them in the hall, wink at them, just once...you dont want them to think your eye is twitching and you want them to be thinking if it was really a wink. that way you will be on their mind all day...

The logic for a burglar alarm is usually simple.  It is not so much the processing but all of the inputs that are important.  Typical inputs are glass breakage, motion detection, magnetic contacts at doors, etc.  The inputs to the burglar alarm detect intrusion into the perimeter.  A microprocessor is needed for motion detection, but most of the rest is very simple logic -- detect a fault (window breakage, door opened, ....) and cause an alarm.

I bought a wonderful webcam with motion detector and infrared from Webcams4u which can be found on Ebay, or on the internet. Their prices are great and I think I paid £10.00 for mine, it also has a built in microphone

Use the java.awt.Robot class mouseMove() method.  You can actually move the mouse, make it click, etc.  This is invaluable for automated testing, self-running demonstrations, etc.  \n\nhttp://java.sun.com/j2se/1.5.0/docs/api/java/awt/Robot.html
