The RAK12019 is a compact UV light sensor module based on the Lite-On LTR-390UV-01, designed for precise UV and ambient light measurement. Ideal for greenhouse monitoring, UV exposure warnings, smart lighting, and IoT environmental sensing, it provides reliable data with low power consumption. With built-in temperature compensation and a high dynamic range, it ensures accurate readings even in varying lighting conditions. Fully compatible with WisBlock, this module supports I2C interface, making integration with Arduino and other microcontrollers easy for quick prototyping and deployment in UV-sensitive applications.

Features:

1. Dual-mode: Ambient Light Sensor (ALS) and UV Light Sensor (UVS)
2. I2C interface (Standard at 100kHz, Fast at 400kHz)
3. Very low power consumption with sleep mode
4. High resolution (13–20 bits effective)
5. Wide dynamic range: 1:18,000,000
6. Human-eye-like spectral response
7. Flicker rejection for 50Hz/60Hz lighting
8. Built-in temperature compensation for accurate readings
