Unit DLight is a digital ambient light detection sensor. The hardware uses a BH1750FVI illuminance sensor IC (I2C interface), with built-in 16-bit AD conversion supporting (1 ~ 65535 lx) illuminance value detection. It features a small size and low power consumption, making it suitable for various illuminance detection and light control adjustment scenarios. Features I2C communication interface (addr: 0x23) Digital conversion of illuminance Low light source dependency (can detect light… (M5Stack U136)
