WeatherShield is a versatile board that hosts the highly accurate BME280 THP sensor (temperature, humidity, atmospheric pressure).

The BME280 sensor was chosen for revision R2 of the WeatherShield because it’s a great sensor that includes all 3 major atmospheric readings we are most interested in. The previous SMD footprint for the Si7021 sensor (used in R1) is left unpopulated and could in fact be used of desired.
