1. Introduction
This Sensor-EXP-EVB is a hardware plugin card for the EFM32 starter kits (STKs). It contains the Si7013 humidity
and temperature sensor as well as the Si1147 UV and proximity sensor. A weather station software demo is
available to download to the Zero or Tiny Gecko STK through simplicity studio. When downloaded to the
EFM32ZG-STK3200 Zero Gecko STK or the EFM32TG-STK3300 Tiny Gecko STK, the demo displays humidity,
temperature, and UV index and performs gesture detection. Right or left gestures move the display type and, on
the temperature screen, up or down gestures move the display between °C or °F.
