LED Light Sensor

A sensor is an electronic equipment which helps to detect events or changes in an environment and send the information to other electronic device which is connected with this sensor.Most of the sensors are sensitive to motion, pictures, magnetic field, gravity, humidity etc. Light sensors help you everyday  by detecting and reacting to diffrent levels of light in appliances, switches and machines. Light sensors vary from those that respond to changes, collect current or hold voltage depending on light levels. Light sensors often detect light that's not visible to the human eye, like x-rays, infrared and ultraviolet light.

LED is also used in light sensors.Due to the high efficiency of LED sensor systems, they are highly sought-after for multiple applications. LED sensors are becoming an ideal option for a light source as it is cost-effective to manufacture and apply, and it can also provide a digital measurement of a light source without the need to waste energy on amplifying the system.
