Comprehensive Guide to Light Sensors | Upgrade Your Smart Life with One Click
1. Core Technology Analysis 1️⃣ Working Principle Light sensors convert light signals into electrical signals through photosensitive elements (such as photodiodes and photoresistors) to detect environmental brightness. Common types include: Photodiodes: High sensitivity, used for precision measurement Photoresistors: Low cost, suitable for basic scenarios Digital Sensors (e.g., TSL2561, BH1750): Built-in ADC chips, directly output digital … Read more
