Abstract
A gas detection device includes an enclosure having an interior chamber, an audio loudspeaker in acoustic communication with the interior chamber of the enclosure, and a gas sensor configured to detect a gas within the interior chamber of the enclosure. The device may include a ventilation port configured to permit two-way gaseous communication between the interior chamber and an atmosphere external to the enclosure, where the atmosphere comprises the gas. The audio loudspeaker is configured to generate a pressure within the interior chamber. The pressure causes a portion of the external atmosphere to be drawn into the interior chamber via the ventilation port. The gas sensor may include an emitter and a receiver. The gas detection device can be integrated into a mobile electronic device, such as a smartphone or tablet computer.
