Non-invasive power meter

Yonas Leguesse’s non-invasive power meter represents a much saver way of measuring electricity consumption without any direct wiring with the mains supply line. It uses a non-invasiveĀ current probe that is clamped around the mains power cable and a spark core module forĀ periodic readings of the current sensor output and sending them to a webserver.
