Bird Electronic brand, 5014 Directional Power Sensor (DPS) and 5015, Terminating Power Sensors (TPS) are USB enabled! These new power sensors are USB 2.0 compliant utilizing a clever locking USB connector to preclude the nuisance of accidental disconnection of the standard “slip-fit” USB connector. Both power sensor series are also capable of measuring True Average Power with an accuracy of 5% and have calibration traceable to National Institute of Standards and Technology (NIST).
