Waveshare TSL25911 High Sensitivity Digital Ambient Light Sensor I2C Interface

This high-sensitivity digital ambient light sensor module, built on the TSL25911 chip, offers a wide dynamic range of 600M:1 and can detect light intensity up to 88,000 lux. Controlled via an I2C interface, it boasts low power consumption and is suitable for operation across various lighting environments.

Manufactured by Waveshare, this module is designed for use with Arduino and Raspberry Pi platforms. Its integration with the TSL25911 chip enables precise detection of light intensity, making it ideal for applications requiring sensitivity to different lighting conditions.

The TSL2591 chip is a highly sensitive light-to-digital converter capable of transforming light intensity into a digital signal output. It incorporates one broadband photodiode (detecting visible and infrared light) and one infrared-responding photodiode on a single CMOS integrated circuit. Two integrating ADCs convert the photodiode currents into a digital output, representing the measured irradiance on each channel. This digital output can be processed by a microprocessor to derive illuminance (ambient light level) in lux, approximating the response of the human eye.

Additionally, the TSL2591 supports a traditional level-style interrupt that remains active until cleared by the firmware, providing further flexibility in its application.
