BH1750 Light Intensity Sensor

SKU: SEN0097

The BH1750 is a digital light intensity sensor with a built-in 16-bit A/D converter that directly outputs calibrated illuminance data from 1 to 65,535 lux. Compared with traditional photoresistors, it offers higher accuracy and stability, and transmits data via the I²C interface, enabling easy integration with microcontrollers and embedded systems. It is ideal for ambient light sensing, smart lighting systems, and display brightness control.
