How do motion detector alarm systems operate?
Motion detector alarm systems operate by using light sources. A beam of light is aimed at the light sensor and anyone who passes causes the sensor to register.
How does a motion detector detect ghosts?
the ghosts move 2 like if u have a room with light sensors the light will still turn on
Why does the security light come on while you are driving?
The security light might come on while you are driving because it has a motion detector on it and when it senses the cars movement the light comes on.
Anyone know where to find a manual for a EML Technologies 3 light motion detector?
I have a manual for the EML Model ES100TMQV3 3 Light Motion detector. My unit has stopped working and I have not been able to contact the company. The 866 number in the manual is no longer in service and their web site is 'under construction' - not a good sign! Seems to me that they are out of business.
What are the different parts of spectrometer?
The basic parts of a spectrophotometer are a light source, a holder for the sample, a diffraction grating in a monochromator or a prism to separate the different wavelengths of light, and a detector.

What are the uses of motion detectors?
The detector senses a person is moving (motion) and a switch is set to on. It depends on why the motion sensor was installed. Maybe an warning alarm is sounded, a camera could begin to record, or a light in the room or passageway is turned on.
Why do they say to only use incandescent lights in security lights with motion sensors?
Incandescent light are the only type of light that has a filament. The filament is the the little piece of wire that glows where the electricity passes through it. All other lights are gas filled. Most motion detectors need to pass a small amount of electricity through the filament to work. The motion detector uses the filament as a neutral wire. The time lag to get a florescent bulb to light up would create too much delay and negate the use of the motion detector. The filament will light up very quickly.
Motion detector security lights won't turn off?
In most motion sensor switches you will have three wires. A black, white and red wire. The black and white (neutral) are used for the electronics in the sensor. These connect to the incoming black and white power. Connect the lamp across the red and the white (neutral). When the sensor detects motion the red wire becomes "hot" and the light will go on.
Is there a siren that can be screwed into the light socket of a motion activated light fixture?
None that I know of, but if you can find a separate siren unit that is powered by 120 volts and in the 5 amp range, it can be hard wired into the motion light.
How does a LED light works in a motion sensor detector?
Two pairs of Infrared LEDs are used as motion sensor detector. The first one is wired to emit LED and the second is wired to transmit a signal when it receives an infrared input. this infrared is reflected back to the receiving LED and then the signal is produced. This signal can be used to open sliding doors, turn on a light or set off an alarm.
Does light behave primarily as a wave or as a particle when it interacts with a detector?
-- If the detector is designed to detect wave characteristics, then light exhibits all the characteristics and behavior of a wave when it encounters that detector. -- If the detector is designed to detect particle characteristics, then light exhibits all the characteristics and behavior of a particle when it encounters that detector.
