SparkFun Weather Shield

The Weather Shield is an easy-to-use Arduino shield that provides access to barometric pressure, relative humidity, brightness, and temperature. There are also connections on this shield for optional sensors such as wind speed, direction, rain gauge, and GPS for location tracking and super-accurate timing.

These weather shields utilize the HTU21D humidity sensor, MPL3115A2 barometric pressure sensor, and ALS-PT19 light sensor, relying on the HTU21D and MPL3115A2 Arduino libraries. Each shield comes with two unoccupied RJ11 connector slots (for optional connection of rain and wind sensors) and a 6-pin GPS connector (for the optional connection of a GP635T GPS module). Finally, each Weather Shield can be powered from 3-6V and features built-in voltage regulators and signal translators.

Note: The Weather Shield is provided as a standalone board. Connectors and additional sensors must be purchased separately. We include two pairs of stackable header pins for free!
