We present an ultra-small wireless sensor node that can be effortlessly attached onto existing electric circuits for real-time energy monitoring systems. Called Granular Radio EnErgy-sensing Node (GREEN), this platform contains an Atmel 2564RFR2 microcontroller with an internal Zigbee-compatible radio transceiver, a battery unit, and an integrated a GMR magnetic sensor to non-intrusively monitor loads...
This paper presents the design, fabrication and experimental results of a self-powered wireless sensor node that can be easily attached to overhead power lines for continuous condition monitoring. The entire sensor node, including a wireless radio platform, a power conditioning circuit and analog sensors, is powered by an AC electromechanical energy harvester, which converts magnetic field energy...
