Data center environmental sensing is provided by a measurement system that detects environmental events from inputs received from a plurality of movable sensors. The sensors are moved in response to detection of an event to a region of the data center associated with the event, providing increased spatial resolution of the measurement in the region of the event. Events such as leakage between hot and cold aisles of a data center can be detected by the system, which may use one or more movable devices that can be moved around, between and over equipment, to carry multiple sensors toward the source of the event, providing both diagnostic and detailed environmental information.
