LED Light Sensors
LED light sensors are devices that detect light and convert it into an electrical signal. They are used in various applications such as lighting control, object detection, and gesture recognition. LED light sensors typically work by emitting light and detecting the reflection of that light. The amount of light reflected back to the sensor is proportional to the amount of light that falls on the object being detected.
Some common types of LED light sensors include phototransistors, photodiodes, and photoresistors. Phototransistors are typically used for light detection in high-power applications, while photodiodes are used in low-power applications, such as in opto-isolators.
