Motion sensor lights work by sending out a signal of some kind. When that signal is broken, the light turns on automatically. Different motion sensors operate with different types of signals. More » Home & Garden Decor

Infrared sensors work by emitting bands or rays of light to determine whether or not there is a certain type of light wavelength in the nearby infrared spectrum. Infrared sensors essentially operate by using LED lights, ... More » Science Physics

Proximity sensors detect objects without coming into contact with them by emitting a high-intensity infrared beam. Some proximity sensors detect reflected light from an object, while others use two infrared beams and rep... More » Technology Mobile

In order to reset motion detector lights, direct the bulbs and sensor to the correct areas, switch the setting to "tester" mode, adjust the sensitivity of the sensor and move the settings back from "tester" mode to "norm... More » Home & Garden Decor Lighting

When choosing quality solar lights for the yard, consider the purpose of the solar lights, the required light intensity, battery life, motion sensor and light sensor. Other factors of consideration include the type of pl... More » Home & Garden Decor Lighting

The fuel level sensor sends a varying signal to the fuel gauge or electronic gadget that triggers the fuel gauge. The components of the sensor, such as float, rod and resistor, work together to give a reading on the leve... More »

Some common parts necessary for repairing a cuckoo clock include the pendulum, chain and gears, all of which have vital functions in the clock's motion mechanisms. The surface of the clock may also be repaired to create ... More » Home & Garden Decor
