EDUMKII OPT3001_Demo

This Example reads the OPT3001 sensor and shows LUX readings in the Energia serial monitor.

Example Video

Hardware Required

  • TI LaunchPad
  • Educational BoosterPack MKII

 

Schematic

None. This basic example just uses your LaunchPad and BoosterPack only.

Code

/*OPT3001_Demo Example
In this example, we will read the various registers available in the OPT3001.
The LUX readings from the OPT3001 are also shown in the Energia serial monitor.
