DC Current Beat: Wireless and Non-Invasive DC Current Sensing Scheme†
AbstractThis paper presents a wireless and Non-invasive DC Current (DCC) sensing scheme as an IoT sensors. A RF module transmits only ID codes to a receiver, and the ID transmissions are called as “DCC Beat”. The interval time of DCC Beats depend on the inductance of ferrite clamp which is non-invasively installed at the wire of the DC current to be measured, so that the interval time corresponds to DC Current. The ID data transmission range reaches up to 50 m with 1.2 mW operating power using a 2.4 GHz RF module. DC current from 0.2 to 4 A can be measured within error of 5.7%.
