photosensor working
A photosensor is a device that changes light into an electric signal. It responds to the intensity or prevalence of light elements and so on, and is a central part of all sorts of technologies. Whatsmore, the main functions of photosensors include light sensing, distance measurement and motion detection. In terms of technology, photosensors come in diverse types such as photodiodes, photoresistors and phototransistors, each with their own particular characteristics suited to different applications. They are made of sensitive semiconductor materials which undergo changes in their electrical properties when exposed to light. Photosensors abound in daily living products such as automatic streetlights, solar panels and even more sophisticated systems like surveillance cameras and medical equipment.
