Product Description
TSL2591 High Dynamic Range Digital Light Sensor Module - Professional-Grade Illumination Analysis for IoT & Automation
The TSL2591 Digital Light Sensor Module delivers unparalleled accuracy across an extreme 600,000,000:1 dynamic range, making it ideal for scientific, industrial, and consumer applications requiring precise light measurement. Leveraging advanced dual-spectrum technology, this sensor captures both visible and infrared light with human eye-equivalent response.
Key Features:
Dual-Spectrum Detection: Separates infrared (700-1100nm) and full-spectrum (400-1100nm) measurements to distinguish natural/artificial light sources.
Wide Detection Range: Senses light from 188μLux (dim moonlight) to 88,000 Lux (direct sunlight) with 16-bit resolution.
I2C Interface: Simple 2-wire communication with fixed 7-bit address 0x29 for compatibility with Arduino, Raspberry Pi, and QWIIC systems.
Low Power Efficiency: 0.4mA active mode and UV Blocking Filter: Ensures accurate color temperature calculations by excluding UV interference.
Applications:
Smart home automation (adaptive lighting)
Greenhouse environmental monitoring
Automotive display systems (sunlight compensation)
Consumer electronics (e-readers, tablets)
Industrial process control
