We were invited today to give a seminar on "How to get started with Embedded Systems" in a local Engineering college. With very little time on hand, wanted to quickly show the capabilities of ESP8266. So I decided to make a temperature humidity logger. With Thingspeak.com, it was extremely easy to log data and even trigger tweets!
