An aspirated-type detector includes a housing with an internal ambient condition sensing region and a sensor carried therein. The housing is perforated with ambient atmosphere inflow ports. A fan or similar device lowers the pressure in the internal region thereby producing a positive inflow of adjacent, external ambient atmosphere into the sensing region. Alternatively, the fan can be operated to inject exterior ambient atmosphere into the sensing chamber under positive pressure. The fan can also be modularized. The detector can incorporate control circuitry for supervisory or signal processing purposes.

A humidifier is provided which lies beneath a bed or other article of furniture. The humidifier is of very shallow height, being much less in height than the length and width. The humidifier includes an open frame resting on the floor, and a sheet of plastic material lying over said frame and on said floor. A pool of water is supported by the plastic sheet material within the frame, and a fan is supported from said frame above said pool of water for moving air across the open surface of said pool of water and out from under said bed or the like.
