Reference
This article delves into the applications and principles of light sensors using the PT550 photodiode, covering driver, library, communication protocols, API descriptions, and demos for various projects, such as smart streetlights and music boxes.
Principle
Light sensors are mainly composed of light-sensitive components. This sensor employs environmentally friendly PT550 photodiode, which can detect the ambient light in the environment and output corresponding voltage according to the intensity of light. The voltage is directly proportional to the light intensity.
