Thanks to our new team member James Tyack for illustrating our green school sensor configuration. This was a quick sketch he made, so I’m not going to complain about the penmanship. (But c’mon James, really.) In case you’re looking for further illumination, we’re looking at the Arduino with WiFi shield sitting in the rain garden transmitting sensor data via the school’s WiFi network. (The Arduino also records sensor data to an SD memory card as a backup.) The sensor readings are sent to a Ruby on Rails server with a database, and displayed on a website.
