🔍 Overview

The GY-302 BH1750 Digital Light Intensity Sensor Module uses the original ROHM BH1750FVI chip and outputs direct Lux (lx) illumination readings. With an I2C interface, it is easy to integrate with Arduino, Raspberry Pi, and various microcontroller platforms. Ideal for ambient light detection, smart lighting, and environmental monitoring projects.

✨ Key Features

• High Accuracy Readings: Built-in 16-bit ADC ensures accurate and stable Lux output.
• Easy I2C Interface: Plug-and-play wiring with most development boards.
• Wide Measurement Range: Supports 0–65535 Lux, suitable for indoor/outdoor applications.
• 5V IO Compatible: Includes level shifting for direct connection to 5V microcontroller IO pins.
• Human-Eye-Like Response: Optical characteristics match human visual sensitivity for realistic light sensing.
