OpenEnergyMonitor EmonTx Shield Power Monitor + ESP8266 + DS18B20 Temperature Probe

Sketch for the OpenEnergyMonitor EmonTX Arduino Shield which monitors input CT1 & a single DS18B20 temperature probe and sends the data to an EmonCMS server via an Huzzah ESP8266 WiFi module instead of using the more traditional RFM69CW RF Module. The ESP8266 is running the EmonESP firmware.

emonESP Firmware: https://github.com/openenergymonitor/EmonESP

THIS SKETCH REQUIRES:

Libraries in the standard arduino libraries folder:

• EmonLib - https://github.com/openenergymonitor/EmonLib.git

• DallasTemperature - https://github.com/milesburton/Arduino-Temperature-Control-Library

• OneWire - https://github.com/PaulStoffregen/OneWire

Also included in the '3D Printed Enclosure' folder is a .STL file and the original Fusion 360 file for an enclosure I designed to house the Arduino & Shield. The hole in the side was incorporated to allow for a DS18B20 probe to be added.
