Adafruit LTR-303 Light Sensor - STEMMA QT / Qwiic

The Adafruit LTR-303 Light Sensor is a versatile and affordable I2C digital sensor designed for seamless integration into various projects. It's perfect for applications like adjusting display brightness, navigating robots towards optimal light, or differentiating between day and night.

This compact sensor provides 16-bit measurements across both Infrared and Visible + IR spectrums. By leveraging its configurable gain and integration time, it effectively measures light from 0 to over 65,000 lux. Additionally, the LTR-303 features alert and IRQ capabilities for ultra-low power scenarios, triggering pins when light levels exceed preset thresholds.

Mounted on a convenient PCB with STEMMA QT connectors, the sensor supports 3.3V and 5V systems, enabling compatibility with platforms like Raspberry Pi, Arduino, and Feather M4. Simplify connections with SparkFun Qwiic-compatible connectors, eliminating the need for soldering by using plug-and-play cables.

The accompanying software includes a comprehensive library for CircuitPython and Python devices, streamlining integration with Raspberry Pi and other systems. Arduino users can benefit from a dedicated LTR-303 library with numerous example applications. Get accurate light measurements effortlessly with the Adafruit LTR-303.
