Attach light intensity sensor

How it's done

Like previous sensor, lux sensor also uses IIC protocol.

For this sensor we will use SLC and SDA pins on Arduino digital side pins. Marks for these two pins are from bottom side. Also, you can use same pins used for RTC. This protocol allow us to use multiple sensors at the same pins.

Connect (lux sensor - Arduino):

  • SCL - SCL;
  • SDA - SDA;
  • Gnd - Gnd;
  • Vcc - 5V.
