Good Value
Sensor works well but the pin headers were not included, had to solder my own. Otherwise great performance.

Perfect for Automation
Using this for smart lighting control. Low power draw is a plus for battery operated devices.

Decent but Fragile
The sensor itself is fine, but the breakout board feels a bit thin. Handle with care during installation.

Excellent Precision
Works flawlessly with my ESP32 project. The lux readings are consistent and match my professional meter closely.
Q: What is the default I2C address for this module?
A: The default I2C address is typically 0x44, but please check the specific datasheet for your variant.
Q: Is 5V logic level safe for the input pins?
A: No, this sensor operates at 3.3V. Using 5V logic directly may damage the module. Use a level shifter.
Q: What is the main difference between OPT3001 and OPT3004?
A: The OPT3004 includes an interrupt pin feature which the OPT3001 lacks, allowing for event-driven readings.
Q: Can this sensor measure UV light intensity?
A: No, this module is designed for visible light detection only and does not measure UV radiation.
Q: Are there any Arduino libraries available for this sensor?
A: Yes, several open-source libraries exist including Adafruit's sensor library which supports this chip.
