The Sense IoT wireless AC Current Meter measures the RMS current of an alternating current (AC) system using a current transformer (CT) that wraps around the “hot” wire of a two wire (hot, common, ground(optional)) power system. The sensor reports Minimum RMS current, maximum RMS current, average RMS current, and amp hours to the Sense IoT system. The Sense IoT system is capable of generating watt hour or kilowatt hour readings as well. • Measures amp hours, max RMS current, min RMS current, and average RMS current • Three different current transducers available: • Low Current: 0-20 amp • Medium Current: 0-150 amp • High Current: 0-500 amp • Capable of generating watt hour or kilowatt hour readings using the Sense IoT portal • Data logging for accumulated amp hour readings • Can notify based on current levels or changes in current levels • Simple and safe installation of current/power measurement hardware, no rewiring required
To measure current, clip the CT around only a single wire of the AC system (clipping around a hot and neutral wire at the same time will result in 0 current readings). After the sensor powers on and connects to the gateway it will begin taking measurements based on the averaging interval (5 seconds default). It will report data to the Sense IoT portal every heartbeat or if the current goes outside of the aware thresholds set in the portal. The sensor reports amp hours, max RMS current, min RMS current, and average RMS current. The Sense IoT portal can also generate watt hour or kilowatt hour readings if a default RMS voltage is set in the portal.
