BH1750 GY-302 Digital Light Sensor / Light Intensity Sensor with I2C

The BH1750 is a light sensor that measures brightness digitally in lux. Thanks to the I2C bus, only two lines to the Arduino are needed. The GY-302 module runs at 3 V to 5 V.

Recommended Accessories:

• Dupont Cable M-F 20cm 20 Pieces

Features:

• Output directly in lux, no conversion needed
• I2C address selectable via the ADDR pin
• Voltage regulator on the module
• Arduino library «BH1750» in the Library Manager

Application Examples:

• Brightness-dependent control of lights and displays
• Measuring room lighting
• Weather stations
