Increasing Adoption of Smartphones and Biometric Devices to Boost Demand for Light Sensors
Light sensors are electrical devices that detect light, detect the level of light emitted by an object, and measure intensity of light. These sensors not only help you every day by detecting lighting, responding to changes in lighting and other objects, but can also be used for robot control and more. Many people even use light sensors as motion detectors. The most common light sensors available are ultrasonic and infrared ones. While both are quite popular they differ mainly in their functionality. For example, an ultrasonic sensor would detect the temperature difference between a set point and the ambient temperature. Infrared sensors can detect the presence of heat. An arguing based light sensor can do a variety of things depending on the sensor's functionality. One example of an infrared sensor is a Light Emitting Diode or LED. An LED can be programmed to detect changes in the ambient environment by changing the current it uses based on its current level of brightness. It
