Light passes through the glass into the greenhouse and heats things up inside the greenhouse. The glass is then opaque to the infrared energy these heated things are emitting, so the heat is trapped inside the greenhouse. It makes sense that a motion detector sensitive to infrared energy cannot...
stopping in the on position. Once the light turns on, flip the switch to the off position and wait five to seven seconds. Turn the switch back to the on position. This should reset the light to only turn on when it senses motion. However, this method ...

In this project, we will go over how to build a motion detector alarm circuit. This is an alarm circuit which will go off when any motion or movement is detected. Once it detects this motion, the circuit will trigger an alarm buzzer to sound which will remain on until the power is dis...
Again, testing one or two is the best option to insure they deliver the quality of light you require. If a CFL is not a suitable replacement for your halogen flood then consider using a motion detector. Motion detectors save energy and money by turning on lights only when needed. Dispose ...
Generally, the larger the aperture, the more light the telescope collects and brings to focus, and the brighter the final image. The telescope's magnification, its ability to enlarge an image, depends on the combination of lenses used. The eyepiece performs the magnification. Since any ...
