Roommate is thinking of building a mini weather station, and now I'm pondering the feasibility of an ESP8266+MSP430G2553 circuit connected to Analog.io
why do you need the msp?
Does the 8266 have on-board ADC?
don't think so, but you can hook up a dedicated adc
I'm also slightly more into the idea of using AT-Command mode of the 8266, since I haven't futz'd around with programming it quite yet.
But I can program an MSP just fine.
