emonTx Shield 4 x CT + Voltage example
An example sketch for the emontx Arduino shield module for
CT and AC voltage sample electricity monitoring. Enables real power and Vrms calculations.
Part of the openenergymonitor.org project
Licence: GNU GPL V3
Authors: Glyn Hudson, Trystan Lea
Builds upon JeeLabs RF12 library and Arduino
emonTx documentation: http://openenergymonitor.org/emon/modules/emontxshield/
emonTx firmware code explination: http://openenergymonitor.org/emon/modul ... x/firmware
emonTx calibration instructions:
http://openenergymonitor.org/emon/modul ... alibration
THIS SKETCH REQUIRES:
Libraries in the standard arduino libraries folder:
- JeeLib https://github.com/jcw/jeelib
- EmonLib https://github.com/openenergymonitor/EmonLib.git
Other files in project directory (should appear in the arduino tabs above)
- emontx_lib.ino

/*Recommended node ID allocation
------------------------------------------------------------------------------------------------------------
-ID- -Node Type-
0 - Special allocation in JeeLib RFM12 driver - reserved for OOK use
1-4 - Control nodes
5-10 - Energy monitoring nodes
11-14 --Un-assigned --
15-16 - Base Station & logging nodes
17-30 - Environmental sensing nodes (temperature humidity etc.)
31 - Special allocation in JeeLib RFM12 driver - Node31 can communicate with nodes on any network
group
