====== Introduction ======
{{ :en:weatherboard_main.jpg?200|}}
The Weather board is an easy to use ODROID-SHOW Add-on that grants you access to UV Index, barometric pressure, altitude, relative humidity, illumination and temperature. Its dimension is only 20 x 20 mm. These Weather board utilize the Si7020 humidity, BMP180 barometric pressure, and Si1132 Ultraviolet(UV) Index with ambient light sensors and relies on some sensor oriented Arduino libraries. Each board comes with a 6-pin connector for ODROID-SHOW connection. All the sensor data goes though I2C communication between sensor ICs and ATMEGA328P MCU on the ODROID-SHOW.

With a few batteries, you can make a portable outdoor weather data capture system. You can also connect it to your host PC or ODROID via ODROID-SHOW to log the various environmental data like a weather station.
