Overview

When the future is dazzlingly-bright, this ultra-high-range luminosity sensor will help you measure it. The TSL2591

luminosity sensor is an advanced digital light sensor, ideal for use in a wide range of light situations. Compared to low

cost CdS cells, this sensor is more precise, allowing for exact lux calculations and can be configured for different

gain/timing ranges to detect light ranges from up to 188uLux up to 88,000 Lux on the fly.

The best part of this sensor is that it contains both infrared and full spectrum diodes! That means you can separately

measure infrared, full-spectrum or human-visible light. Most sensors can only detect one or the other, which does not

accurately represent what human eyes see (since we cannot perceive the IR light that is detected by most photo

diodes)
