Abstract
A humidifier device includes an output device, an atomizer enclosure having a first opening that is operable to be open and closed and a second opening, an atomizer within the atomizer enclosure configured to produce moisture and to output the moisture through the second opening of the atomizer enclosure, a humidity sensor configured to sense humidity levels, and control circuitry configured to control the atomizer and to determine whether the humidity levels sensed by the humidity sensor are indicative of the first opening of the atomizer enclosure being open. The output device is configured to, in response to determining that the humidity levels sensed by the humidity sensor are indicative of the first opening of the atomizer enclosure is open, output an alert indicative of the first opening of the atomizer enclosure being open.
