Modulino Light multifunctional optical sensor module: ambient light detection, RGB color recognition, and infrared light sensing; dual Qwiic (I2C) interfaces.

Multifunction optical sensor

Ambient light | RGB color | IR sensing

The Modulino™ Light is a multifunctional optical sensor module integrating ambient light detection, RGB color recognition, and infrared light sensing. Equipped with the LTR-381RGB-01 sensor, it can collect ambient light intensity, red/green/blue color components, and infrared light data in real time, providing optical sensing capabilities for smart devices.
The module uses I2C communication and features dual Qwiic connectors, enabling quick connection to Arduino development boards and other Modulino™ series modules without complex wiring. It is suitable for smart lighting, color recognition, ambient light monitoring, and interactive electronic projects.

Product features

Ambient light detection: senses changes in surrounding ambient light, providing data support for automatic brightness adjustment and smart lighting.
RGB color recognition: separately detects red, green, and blue light components, and can be used for object color recognition and classification.
Infrared light sensing: supports infrared light detection, extending optical sensing applications.
LTR-381RGB-01 sensor: integrates multi-channel optical detection functions to enable the acquisition of multiple types of optical data.
I2C digital communication: reads sensor data through the I2C interface, making it easy to integrate with microcontrollers.
Qwiic plug-and-play: equipped with dual Qwiic connectors, supporting cascaded expansion of Modulino™ modules.
Arduino ecosystem compatible: supports the Arduino Modulino™ library for rapid development.
