In my previous post, I finished the Web Service that the ESP8266 uses to upload well tank temperatures (and eventually a depth estimate) to a cloud database. In this post, I turn to the mechanical design of the case for the RJ45 jacks for the 1-wire interface.

Since my last post, I’d ordered and received some RJ45 jacks and breakout boards from Sparkfun.  I’m planning to use an RJ45 jack on a half-sized breadboard as the interface between the ESP8266 Thing Dev board and the 1-wire bus.
