The SLSTK3201A Zero Gecko Starter Kit includes a Humidity/Temp/Optical Expansion Board (BRD8001A) and a EFM32ZG-STK3200 Zero Gecko STK. This document describes the Humidity/Temp/Optical Expansion Board and a weather station demo based on it.
The Humidity/Temp/Optical Expansion Board is a hardware plug-in 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.
