light sensor to save money

How many are the times that you have to ask the little ones (and big) to leave the room to turn off the lights? Millions. It’s something many forget, leave the room and turn off the lights. What in these times is a double damage.

First, because the planet’s energy situation is not to go around leaving lights on out there. And secondly because your pocket can not afford the family forgetfulness.
That’s why a product like the one we present below is ideal sensors busy / free.

These are systems that are installed in place of traditional light switches, the difference is that the light turns on automatically when someone enters the room and turns off when the room is empty. All automatically, without having to worry.
A light sensor, as its name suggests, is a device that is used to detect light. There are many different types of light sensors, each of which works in a slightly different way. A photocell or photoresistor, for example, is a small sensor that changes its resistance when light shines on it; they are used in many consumer products to determine the intensity of light. A charged coupled device (CCD) transports electrically charged signals, and is used as a light sensor in digital cameras and night-vision devices. Photomultipliers detect light and multiply it.

Devices that include these sensors have many uses in scientific applications, but are also found in items that people encounter each day. A simple light sensor may be part of a security or safety device, such as a burglar alarm or garage door opener. These types of devices often work by shining a beam of light from one sensor to another; if the light is interrupted, an alarm sounds or the garage door won’t close.

Many modern electronics, such as computers, wireless phones, and televisions, use ambient light sensors to automatically control the brightness of a screen, especially in low-light or high-light situations. They can detect how much light is in a room and raise or lower the brightness to a more comfortable level for the user. Light sensors also may be used to automatically turn on lights inside or outside a home or business at dark.
