Digital LTR390 Ultraviolet (UV) Sensor

The UV Sensor (C) is an I2C digital UV sensor module that incorporates the LTR390-UV-01. It is designed for measuring ultraviolet rays as well as visible light and provides light intensity value output. The UV Sensor features sensitive detection, fast response, and a small form factor. 

Connections:

VCC > 3.3V/5V power input

GND > GND

SDA > Connects to MCU I2C data pin

SCL > Connects to MCU I2C clock pin

INT > GPIO input, triggering pulse signal on interruption

Connecting with Raspberry Pi:

Connecting with Arduino board:

• Incorporates LTR390-UV-01, for measuring ultraviolet rays and visible light
• Embedded ADC, direct light intensity value output via I2C bus, less noise interference
