Solid performance
Used this in a mobile robot to detect ambient conditions. It responds quickly to changes. Would give 5 stars if it came with header pins pre-soldered.

Excellent for learning
Bought this for a university project on smart lighting systems. The documentation provided by the seller helped me get started quickly. Very reliable data output.

Best value light sensor
Compared to other sensors in this price range, the OPT3004 offers superior precision. The human-eye spectral response makes a real difference in automatic brightness applications.

Great dynamic range
I needed a sensor that could handle both dark rooms and direct sunlight. The OPT3001 handles the full range without saturating. Integration with ESP32 was seamless.

Accurate but small pins
The sensor accuracy is impressive and matches the datasheet specifications perfectly. My only complaint is that the pins on the breakout board are a bit close together for standard breadboards without an adapter.

Perfect for Arduino Projects
This module works flawlessly with my Arduino Uno. The I2C library is easy to use, and the readings are very stable even under fluctuating light conditions. Highly recommended for hobbyists.
Q: Can I use this with a Raspberry Pi?
A: Absolutely. Since it communicates via I2C, you can easily connect it to the GPIO pins on any Raspberry Pi model using Python or C++ libraries.
Q: Does this module come with header pins included?
A: The module typically ships without header pins soldered to allow for flexible mounting options, but headers are often included in the bag for you to solder yourself.
Q: What is the maximum lux this sensor can measure?
A: The sensor has a wide dynamic range and can accurately measure up to approximately 83,000 lux, which covers everything from moonlight to direct sunlight.
Q: Does it support interrupt signals for low power modes?
A: Yes, the OPT3001/02/04 series includes programmable threshold interrupts, allowing your microcontroller to sleep until specific light levels are detected.
Q: Is this compatible with 5V logic levels?
A: Yes, the module supports a supply voltage up to 5.5V and features level shifting, making it safe to use with both 3.3V and 5V microcontrollers.
