Adafruit LTR-303 Digital Light Sensor Module - STEMMA QT / Qwiic I2C
The Adafruit LTR-303 is a high-precision digital ambient light sensor module with an I2C interface and STEMMA QT/Qwiic connector. It provides 16-bit resolution lux measurements across six dynamic ranges (0.01 to 64k lux) and is compatible with 3.3V/5V systems like Arduino, Raspberry Pi, and ESP32.
Features
- High-resolution 16-bit digital light sensor (LTR-303ALS) with human-eye spectral response.
- I2C interface (address 0x29) with Fast Mode (400kHz) and interrupt output capability.
- Six configurable dynamic ranges from 0.01 lux to 64,000 lux for precise ambient light measurement.
- Wide 3.3V to 5V DC operating range with onboard voltage regulation and STEMMA QT/Qwiic connectivity.
- Built-in temperature compensation and automatic rejection of 50/60 Hz lighting flicker.

The Adafruit LTR-303 Light Sensor Module integrates the LTR-303ALS digital ambient light sensor, designed to closely match the photopic response of the human eye. It provides accurate lux measurements by separately detecting infrared and visible+IR light, enabling precise ambient light level monitoring for display backlight control and environmental sensing.
The module features a configurable gain and integration time architecture, offering six dynamic measurement ranges for optimal performance from dark rooms to direct sunlight. Its I2C interface supports fast communication and includes an interrupt pin for low-power, event-driven operation, making it suitable for battery-powered IoT devices and embedded systems.
