Adafruit TSL2591 High Dynamic Range Digital Light Sensor - STEMMA QT
The Adafruit TSL2591 is a high-precision digital light sensor with an ultra-wide dynamic range, ideal for Arduino, Raspberry Pi, and other 3.3V/5V microcontrollers. It provides separate infrared and full-spectrum light measurements for accurate human-eye response approximation.
Features
- Ultra-wide dynamic range from 1 to 600,000,000 counts for extreme lighting conditions.
- Separate infrared and full-spectrum photodiodes for precise human-visible lux calculations.
- Onboard ADC and I2C interface (addresses 0x29 & 0x28) compatible with any microcontroller.
- Plug-and-play connectivity via STEMMA QT / SparkFun Qwiic compatible 4-pin JST-SH connector.
- Low power consumption: ~0.4mA active, <5 µA in power-down mode for data-logging applications.

The TSL2591 luminosity sensor utilizes advanced dual-diode architecture, combining an infrared-sensitive photodiode and a full-spectrum (visible + IR) photodiode. This allows the integrated analog-to-digital converter (ADC) and digital signal processor to calculate precise illuminance in lux by subtracting the IR component, closely matching the photopic response of the human eye.
Its configurable gain and integration time settings enable on-the-fly adaptation to light levels from a dark 188 µLux up to a bright 88,000 Lux. The sensor’s all-digital I2C output ensures stable, noise-immune readings, making it suitable for integration into professional lighting control systems, environmental monitoring stations, and portable instrumentation.
