This is a project to monitor the number of birds that visit my bird feeder, as well as record the amount of time spent feeding. I used an Arduino Yún and a capacitive touch sensor, Adafruit CAP1188, to detect and record the birds feeding. On a routine basis, the accumulated data is sent to a Google Docs spreadsheet to record the number and time spent by the birds visiting the feeder.
Data is only transmitted during a set period of time prior to sunrise and after sunset.
These are a list of the parts that I used to assemble my project. You could use a variety of project boxes to create your project, but these are the items I had on hand at the time.
