Unit DLight
SKU:U136
Description
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 sources: incandescent, fluorescent, halogen, white LED, sunlight)
- Detection range (1 ~ 65535 lx)
- HY2.0-4P interface
Includes
- 1 x Unit DLight
- 1 x HY2.0-4P Grove connection cable (20cm)
