BBWeatherStation

BeagleBone (BB) Web Server offering weather measures taken from Weather Capes of other BeagleBones. This is a simple project to use data measured by the Weather Cape over the BB.

Project

Project developed by:

• Marcos Canales Mayo
• Carlos Escuín Blasco

Hardware

• BB White Rev A6a
• Weather Cape

Software

• Angstrom distro
• Web server lighttpd
• PHP5 with PHP-CGI

Weather data collection

Data collected reading inputs under /sys/bus/i2c/devices/i2c-1/ folder:

• Temperature (ºC)
• Pressure (bar)
• Humidity (%)

Periodically (using cron or a background service), every BB reads its parameters and sends them to the main BB in order to be stored there.

Current version

• BB2 periodically measures the weather params (temperature, pressure and humidity) and sends them to BB1
• BB1 periodically measures the weather params and stores them. This BB also runs a web server to show collected data among every BB.
