EnergyMonitor

Arduino energy monitor, using SCT-013-030 current sensors

Project Links :

This is a full energy monitor project :

  • You can manage 1 to 6 sensors.
  • You can configure it through USB (see below).
  • It can communicate through USB, with any homemade software.
  • It can communicate with any Home Automation System supporting MySensors (I'm using Domoticz).
  • Full source is provided, you can customize it.

Needed parts :

Instructions :

  • Before to print case, you can specify how many sensors you have.
    • You can define the exact number of sensors, or plan more. Each socket will be pre-cut for future use.
  • Follow joined scheme for assembly.
    • Each sensor have to be connected to A0, A1 and so on...
  • Upload sketch to the Arduino Nano.
  • Connect it to any computer for configuration (see below).
  • Let's play...

Configuration parameters :

  • Number of sensors,
  • Sensor calibration (Vrms, ICal, IOffset),
  • Sample frequency,
  • Transmission frequency,
  • Toggle MySensors on/off,
  • Toggle serial output on/off.

Configuration will be saved to eeprom.

Using serial console, you can communicate with the sensor. For example, using minicom (? for show help) :

$ minicom -b 115200 -D /dev/ttyUSB0

Energy Sensor (can use up to 6 sensors)
F0: : Sample frequency in seconds (F0:5)
F1: : Send frequency in seconds (F0:60)
E#:[0|1] : Enable Sensor # (E0:1[;E1:1])
V<#:val> : Set Vrms (V0:230[;V1:230])
C<#:val> : Set ICal (I0:29.95[;I1:29.98])
O<#:val> : Set intensity offset (O0:0.05[;I1:0.07])
S[0|1]   : Toggle Serial output
T[0|1]   : Enable MySensors transmission
M<#>     : Sensor mode (1: power, 2: current, 3: power+current)

Warning : If you are using SCT-013-000 instead of SCT-013-030, you have to add burden resistor. NRF24L01 may have connection issues. You have to add 10µF capacitor between PWR and GND.

You'll be handling dangerous voltages. I decline any responsibility in case of any incident or accident.
