Abstract
Environmental sensing devices, systems and methods are provided. In one embodiment, an environmental sensing device includes an environmental sensor and an internal signal generator. The environmental sensing device may be configured to be mechanically coupled to one or more interior surfaces of an enclosure. The environmental sensor may be operable to detect one or more substances within the enclosure and provide a status signal to the internal signal generator corresponding to the presence of the one or more substances. The internal signal generator may be operable to generate a mechanical report sequence corresponding to the status signal. The mechanical report sequence may be a series of mechanical pulses applied to an interior surface of the enclosure.
