About this product
A digital ambient light sensor module built around the OPT3001 chip, which measures illuminance in lux. Its spectral response is close to the human eye and it rejects most infrared light, so readings track perceived brightness better than basic LDR sensors. It communicates over I2C, making it straightforward to read from Arduino, ESP32 or STM32 boards.

How do I change or check the I2C address?
The OPT3001 ADDR pin sets the address: GND gives 0x44 (default), VDD gives 0x45, SDA gives 0x46 and SCL gives 0x47. Run an I2C scanner sketch to confirm the address your board uses.
What supply voltage should I use?
The OPT3001 chip itself operates from 1.6 V to 3.6 V. Check the module's supply input and I2C pull-up levels match your board (3.3 V or 5 V) before connecting power.
