Abstract
The present disclosure provides methods and systems for initiating sealed sensor units in the field. A packaged sensor unit may include a sensor module, an activation mechanism and an internal battery, all situated in a sealed enclosure. In some cases, the sealed enclosure may be devoid of any externally accessible switches. A pre-defined triggering stimulus may be applied to the packaged sensor unit, and the pre-defined triggering stimulus may be detected via the activation mechanism. In response to the activation mechanism detecting the pre-defined triggering stimulus, the internal battery may be connected to the sensor module. Prior to detecting the pre-defined triggering stimulus, both the sensor module and the activation mechanism may draw no power from the internal battery of the packaged sensor unit. In some cases, the activation mechanism, once activated, irreversibly couples the power supply to the sensor module.
