Unit DLight
Description
Unit DLight is a digital ambient light detection sensor that uses the BH1750FVI illuminance sensor IC (I2C interface). It has a built-in 16-bit AD converter supporting illuminance value detection ranging from 1 to 65535 lx. It is characterized by its small size and low power consumption, making it suitable for various illuminance detection and light control adjustment scenarios.
