the spark counter is a custom electricity meter with wireless data logging capability.
on one side I have:
* peacefair PZEM-004 power meter to measure the electricity consumption
* ATmega328P micro-controller to read the measurements out
* nRF24L01+ radio to transmit the values
on the other side:
* nRF24L01+ radio to receive the values
* Raspberry Pi single board computer to store the measurements in an influxDB time series database
* grafana graphical monitoring tool to display the electricity consumption
more information is available in the [wiki](https://wiki.cuvoodoo.info/doku.php?id=spark_counter).
