OpenEnergyMonitoring – Calibration
As the emon’s are now up and running, the next big thing needs to happen, calibrating the sensors.. There is a good wiki on how and what to do: http://openenergymonitor.org/emon/buildingblocks/calibration What do we need to calibrate? emonTX: AC Voltage, in combination to the AC-AC power adapter AC current used, compared to what is read by the coil sensors Following the guide, these number reflect the Node10: The new calibration coefficient can be calculated by: New calibration = existing calibration ×…
