Sensor pinout description from Adafruit

The UV ultraviolet light sensor can be connected in two ways. The first one uses solder fields to which a 2.54 mmgoldpinstrip (included in the kit) should be soldered. Alternatively, the sensor also has aSTEMMA QT /Qwiicconnector, which allows you to quickly and conveniently connect the module without soldering.

  • VIN- power supply pin with voltage range from 3 V to 5 V DC.
  • 3Vo- supply pin with voltage 3,3 V.
  • GND- system ground.
  • SCL- I2C logic pin, communication interface clock line pin.
  • SDA- I2C logic pin, communication interface data line pin.
  • INT- main interrupt pin, can be configured according to individual needs.
