The WeMos D1 mini fritzing part: https://github.com/heskew/things-aws-iot-soil-monitor/blob/master/fritzing/WeMos%20D1%20mini.fzpz

It's lacking a PCB view but hopefully the breadboard and schematic views could be useful.

It's lacking a PCB view but hope this could be useful for others with usable breadboard and schematic views.

sensor and monitor/display

ESP8266 based soil moisture sensor and ESP8266 based monitor with an Adafruit NeoPixel Feather display, each individually connects to AWS IoT so the sensor(s) and monitor can be anywhere (power and wifi depending). /sensor: WeMos D1 Mini based sensor code /monitor: Adafruit Feather HUZZAH ESP8266 based monitor code

aws-sdk-arduino

**use the iot-get-shadow-and-cleanup branch** Forked fork of https://github.com/awslabs/aws-sdk-arduino. Initial fork (https://github.com/svdgraaf/aws-sdk-arduino) adds AWS IoT and ESP8266 support. I'll get a pr out soon to try to consolidate the fork-ness of this.
