Abstract
A system, device, and method for monitoring and signaling personnel presence uses a personnel presence sensor capable of detecting physical presence and proximity of a person within a space. Personnel presence monitoring/signaling logic determines any of a number of personnel presence conditions based upon personnel presence information obtained from one or more such sensors, and may signal any of a number of personnel presence conditions. The personnel presence monitoring/signaling logic may be coupled to a communication network for remote monitoring and control.
