If you are looking to test a lux value of light with Arduino, then this project is suitable for you its easy and cool! Just connect the BH1750 module, upload the code, and run the serial monitor.

EXPANDED TECHNICAL DETAILS

Digital Photometric Measurement

This project provides a professional-grade light meter capable of measuring ambient light levels from 1 to 65,535 Lux with high precision.

  • BH1750 I2C Interface: Communicates with the digital light sensor via the I2C protocol. Unlike simple LDRs which are non-linear, the BH1750 provides a direct digital output that is calibrated to the human eye's spectral response.
  • Automatic Sensitivity Scaling: The firmware automatically shifts between "H-Resolution" and "L-Resolution" modes based on the lighting conditions, ensuring accurate outdoor readings (10,000+ Lux) and dim indoor readings.

Practical Application

  • Industrial Lighting Audit: Ideal for checking if a workspace or plant-growth chamber meets specific Lux standards for safety or optimal photosynthesis.
