The project needs a processor, preferrably with wireless networking capabilities. Originally I had considered using a ESP8266 but the recent Pi Zero contest has brought my attention to the Pi Zero again. A popular platform amongst other hackers I know I have direct access to a lot of information about Pi's, not to mention the vast amount of information already available on the internet. Having only made a single project on a Pi previously it is a good opportunity to expand my experience with the platform and the small zero seems perfect for the job. Perhaps the Pi could even host a website displaying sensor output - more about that it the next update.
