Optical Sensors are components that detect light and convert it into an electronic signal. Devices in this category include ambient light sensors, IR sensors, UV sensors, camera modules, distance measuring sensors, image and camera sensors, photo detectors (CdS cells, logic output, remote receivers), photodiodes, industrial photoelectric, photointerrupters (slot type - logic output, transistor output), photonics (counters, detectors, single photon counting modules), phototransistors, reflective (analog output, logic output), and more.
