|SparkFun Weather Shield for Arduino with quarter for size reference.|
SparkFun’s Weather Shield for Arduino can be used to build an Arduino-controlled weather monitoring station that measures barometric pressure, relative humidity, luminosity, and temperature. This shield incorporates a HTU21D humidity sensor, MPL3115A2 barometric pressure sensor, and ALS-PT19 light sensor and relies on the HTU21D and MPL3115A2 Arduino libraries. The shield has a built-in 3.3 V voltage regulator that lets it operate at 3 V to 10 V.
For documentation and resources to help you use this weather shield, including the HTU21D and MP3115A2 Arduino libraries, see the guide on SparkFun’s site. Datasheets for the individual sensors can be found under the Resources tab.
- HTU21D Humidity and temperature sensor
- MPL3115A2 Barometric pressure sensor
- ALS-PT19 Light sensor
- Operating voltage: 3 V to 10 V
- Built-in voltage regulators and signal translators
- Typical humidity accuracy of ±2 %
- Typical pressure accuracy of ±50 Pa
- Typical temperature accuracy of ±0.3°C
This shield ships with all of its surface-mount parts populated. However, header pins are not included. Our 0.1″ male headers are compatible, but if you plan on stacking multiple shields, we recommend our stackable 0.1″ female header set for Arduino shields.
An Arduino is not included.
Note: SparkFun calls this product the “Weather Shield” SKU: DEV-12081. It replaces the older USB Weather Board V3.
