## Description

The SparkFun Photon Weather Shield is an easy-to-use add-on board that grants you access to barometric pressure, relative humidity, and temperature. There are also connections on this shield to optional sensors such as wind speed, direction, rain gauge and soil readings!

These Weather Shields utilize the Si7021 temperature/humidity and MPL3115A2 barometric pressure sensors. Each shield comes with two RJ11 connectors (for optional hookup of rain and wind sensors) and a 3-pin soil temperature and moisture hookup. Finally, each Weather Shield can attach effectively and easily to your Photon in no time at all!

The Particle Photon is a tiny WiFi development kit for creating connected projects and products. Sporting a 120MHz ARM Cortex M3 and built-in WiFi, the Photon is not only powerful but easy to use. The small form factor is ideal for IoT projects with cloud connectivity.

**Features:**

- Humidity/Temperature Sensor — Si7021
- Barometric Pressure — MPL3115A2
- Headers and Connectors Pre-Soldered
- Compatible with the Photon and the Core
