Abstract: A sensor for measuring current flow includes a housing containing a power generation circuit and a current measurement circuit. The sensor is entirely self-contained and is non-invasively attachable to a conductor. The sensor is self-powered using energy harvested by the power generation circuit. The current measurement circuit allows for continuous, uninterrupted measurement of at least one property related to the flow of current through the conductor. The sensor wirelessly transmits data related to the measured current flow to a computing device. The sensor may be used with other similar sensors to form a wireless sensor network that monitors one or more properties related to the flow of current through one or more conductors within a system.

Abstract: A system for monitoring and controlling building equipment includes a near field communications (NFC) tag, a temperature sensor, a mobile device, and a controller. The NFC tag is located within a building space and stores a tag ID uniquely identifying the NFC tag. The temperature sensor is associated with the building space and configured to measure a temperature of the building space. The mobile device reads the NFC tag and obtains the tag ID from the NFC tag via NFC. The controller receives the tag ID from the mobile device and uses the tag ID to identify the temperature sensor associated with the building space. The controller receives the measured temperature from the temperature sensor and provides the measured temperature to the mobile device. The mobile device displays the measured temperature via a user interface of the mobile device.
