Digital UV Sensor

Ultraviolet Ray Sensing & Ambient Light Intensity Measuring

Direct Outputs UV Index And Light Intensity Value

Features

The UV Sensor (C) is an I2C digital UV sensor module which incorporates LTR390-UV-01, designed for measuring ultraviolet ray as well as visible light, and providing light intensity value output. With features including sensitive detection, fast response, and small form factor, the UV Sensor (C) integrates the main sensor LTR390-UV-01 on its 27 × 20mm body, allowing easy integration into other devices.

How do I connect and read data from the sensor with a microcontroller?

It uses an I2C interface with a fixed address of 0x53. Connect VCC to 3.3V or 5V, GND to ground, SDA to the MCU I2C data line and SCL to the I2C clock line, then read the UV index and light intensity value via I2C. An interrupt output is available with programmable upper and lower thresholds.

What boards or ecosystems is this module compatible with?

It supports Raspberry Pi, Arduino and STM32 platforms. The package includes development resources and a manual with examples for these boards.

What does the sensor measure and what data does it output?

It measures ultraviolet light in the 280 to 430 nm range and ambient light intensity. It outputs the UV index and the light intensity value via the I2C interface.

What are the physical specifications and mounting options?

The module has a 27 by 20 mm body with a 2.0 mm mounting hole. It operates at 3.3V or 5V and uses an onboard voltage translator for compatibility.

What is included in the package and what resources are available?

The package includes the UV Sensor C and a PH2.0 5PIN wire. It also includes development resources and a manual with examples for Raspberry Pi, Arduino and STM32.
