Description

This Gravity: LTR390-UV sensor from DFRobot provides both ambient light and UV sensing with UV spectral response from 280nm to 430nm and raw data output. It features high sensitivity, quick response, and strong anti-interference ability.
With built-in ADC and MCU, this UV module can convert light data to a digital signal capable of being directly output via I2C or UART interface. It can be used for light experiments, outdoor UV detection, and other scenarios requiring UV or ambient light monitoring.

Applications:

UV intensity detection
Light intensity detection
Weather experiments for teaching
Light detection experiments
Devices for monitoring UV index
Devices for outdoor UV detection

Features:

Support I2C and UART communication
3.3V & 5V compatible
13 to 20 bits effective resolution
Adjustable gain range: 1, 3, 6, 9 and 18
Interrupt function, programmable upper and lower thresholds
Close to human eye spectral response
