LDR resistors mainly involves in … This can be used by connecting to an electrical or electronic circuit in an extensive range of applications like sunset to sunrise lighting that mechanically turns on whenever intensity of light is low. IR Sensors or Infrared Sensor are light based sensor that are used in various applications like Proximity and Object Detection. In some cases, a faulty sensor will keep the lights from turning on automatically. Your email address will not be published. We have summarised our broad planning and design expertise in architectural lighting for you. Light is an electromagnetic radiation with a much shorter wavelength and higher frequency than radio waves. Another common application of light sensor is night lamp. In museums, the lighting on sensitive exhibits can be reduced when there are no visitors. Work – light for office- and administrative buildings. IR sensor is an electronic device, that emits the light in order to sense some object of the surroundings. Some of its features are heat and motion sensing. Ambient Light Sensing Application Ambient light sensors are included in many laptops and cell phones to sense the environment lighting conditions, allowing for adjustment of the screen's backlight to comfortable levels for the viewer.
