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 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.
