LIGHT SENSOR
LIGHT SENSOR
A light sensor generates an output signal indicating the intensity of light.
The light sensor is a passive sensor that convert this “light energy” into an electrical signal output. Light sensors are more commonly known as “Photoelectric Devices” or “Photo Sensors” because they convert light energy (photons) into electricity (electrons).
Light Sensor in micro:bit
Light Sensor in micro:bit
Micro:bit are using some light-emitting diodes or LEDs on the micro:bit to detect light. LEDs can be used in Reverse. If you shine a light on an LED, it will produce a very small amount of current and we can use that to crudely measure how bright a room is.
