SEN0540

SEN0540 is a Gravity: LTR390 UV Light Sensor board. This sensor provides ambient light and UV detection, with high sensitivity and anti-interference. It outputs digital signals via I2C/UART for various applications. 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.
