Weather Shield Hookup Guide
Weather Shield Overview
The Weather Shield is an easy to use Arduino shield that grants you access to barometric pressure, relative humidity, luminosity, and temperature. There are also connections to optional sensors such as wind speed/direction, rain gauge, and GPS for location and super accurate timing.
