About this item

The TSL2591 High Dynamic Range Digital Light Sensor is an advanced I²C-based sensor designed to measure ambient light with exceptional sensitivity and precision. It features a broad dynamic range of 1 to 600,000,000 counts, enabling accurate light detection from as low as 188 µLux to up to 88,000 Lux. The sensor combines both visible and infrared photodiodes, allowing for comprehensive light measurement. With a low operating current of approximately 0.4 mA during active sensing and less than 5 µA in power-down mode, it is suitable for low-power applications. The TSL2591 operates within a voltage range of 3.3V to 5V and is compatible with various microcontrollers, including Arduino and Raspberry Pi. Its small form factor and I²C interface make it ideal for integration into projects requiring precise ambient light sensing, such as display backlight control, camera exposure adjustment, and environmental monitoring systems.
