| YoMo board with electronic components |
We introduce our recently developed smart metering board called YoMo (You only meter once). The board is an extension board compatible to Arduino boards. YoMo offers features such as:
- measuring active, reactive, apparent power, current, and voltage
- switching loads up to 20A,
- adjustable sampling frequency and
- open-hardware design and open-source firmware

The smart meter platform, provided as open hardware, is designed with a connector interface compatible to the Arduino platform, thus opening the possibilities for smart meters with flexible hardware and computation features, starting from low-cost 8 bit micro controllers up to powerful single board computers that can run Linux. The metering platform features a current transformer which allows a non-intrusive installation of the current measurement unit. The suggested design can switch loads, offers a variable sampling frequency, and provides measurement data such as active power, reactive and apparent power. Results indicate that measurement accuracy and resolution of the proposed metering platform are sufficient for a range of different applications and loads from a few watts up to five kilowatts.
