Barometric condition is one of the criteria used to predict coming change in weather and deduce altitude
above sea level. Here is a demo to show you how to read the barometric data from this Grove - Barometer
Sensor.
1. Connect it to IIC port of Seeeduino or Grove - Base Shield via a Grove cable. And connect Arduino to PC
via a USB cable.
2. Download the library Grove_Barometer_HP20x;Unzip it into the libraries file of Arduino IDE by the
path: ..\arduino-1.0.1\libraries.
3. Create a new Arduino sketch and paste the codes below to it or open the code directly by the path:
