SparkFun Weather Shield

The SparkFun Weather Shield is a versatile Arduino shield that provides access to a range of weather-related data, including barometric pressure, relative humidity, light levels, and temperature. This shield also offers connections for optional sensors, enabling the measurement of wind speed and direction, rainfall, and GPS for precise location and timing data.

The Weather Shield employs the Si7021 sensor for humidity and temperature measurements, the MPL3115A2 sensor for barometric pressure, and the ALS-PT19 sensor for light levels. The functioning of the shield is dependent on the Si7021 and MPL3115A2 Arduino libraries.

The shield includes two unoccupied RJ11 connector spaces, which can be used for the optional connection of rain and wind sensors. Additionally, there is a 6-pin GPS connector for the optional connection of a GP-735 GPS module. The Weather Shield can operate from 3.3V up to 16V and features built-in voltage regulators and signal translators.

Note: The Weather Shield is sold as a standalone board. Headers, connectors, and additional sensors are not included and must be purchased separately. It is designed for use with 5V boards, such as the SparkFun RedBoard and Arduino Uno. It is not compatible with 3.3V boards without modification.

With the SparkFun Weather Shield, you can create a comprehensive weather station right in your backyard or even a portable device for on-the-go weather updates. Whether you're a hobbyist looking to explore the fascinating world of meteorology or a professional requiring accurate weather data for research or planning, this shield is a perfect choice.
