“Want to measure light intensity easily? Try the BH1750 (GY-302) Light Sensor!”

Looking for a light sensor that gives digital lux readings directly, instead of raw analog voltages? The BH1750 (GY-302) answers that need — it outputs light levels over I²C as real-world lux values. 

Need a sensor that works with 3.3 V–5 V logic and fits easily into your Arduino, ESP32 or Raspberry Pi project? BH1750 is fully compatible. 

Want a wide measurement range — from dim indoor lighting to bright sunlight? BH1750 covers from 1 to 65,535 lux. 

Concerned about power consumption for battery-powered or IoT builds? BH1750 has low current draw while still providing high-sensitivity measurements. 

Planning automatic light-based control — e.g. for room lighting, ambient sensing, or display brightness adjustments? BH1750’s accurate lux output makes it perfect for such automation or environmental monitoring tasks. 

Whether you need to detect day vs night, adjust brightness dynamically, or log ambient light data — BH1750 (GY-302) is a simple, reliable, and high-precision solution.
