Gravity LTR390 UV Light Sensor I2C and UART

The Gravity: LTR390-UV sensor from DFRobot measures ambient light and UV within a range of 280nm to 430nm. It features high sensitivity, quick response time, and low susceptibility to interference. Equipped with integrated ADC and MCU, the module outputs digital signals via the I2C or UART interface. It is perfectly suitable for outdoor UV detection and light experiments. 

Features: 

• Supports I2C and UART communication 
• 3.3V & 5V compatible 
• 13 to 20 bit effective resolution 
• Adjustable gain range: 1, 3, 6, 9, and 18 
• Interrupt function, programmable upper and lower thresholds 
• Spectral sensitivity close to the human eye
