BH1750 Light Intensity Module

The BH1750 Light Intensity Module is a high-precision digital ambient light sensor designed to measure light intensity in lux. It uses the BH1750FVI sensor and communicates via the I²C interface, making it extremely easy to integrate with popular microcontrollers such as Arduino, ESP8266, ESP32, Raspberry Pi, and other development boards.

Unlike basic LDR sensors, the BH1750 provides accurate, calibrated digital output that closely matches human eye perception. It is ideal for applications that require reliable and real-time ambient light measurement, such as automatic brightness control and smart lighting systems.
