Various arrangements for determining an atomization element of a nebulizer is dry are presented. The vibratable element of the nebulizer may be energized with an electrical signal that sweeps from a first frequency to a second frequency. While energizing the vibratable element of the nebulizer with the electrical signal that sweeps from the first frequency to the second frequency, a sequence of impedance values of the vibratable element of the nebulizer may be measured. The sequence of impedance values of the vibratable element of the nebulizer may be analyzed to determine if the atomization element of the nebulizer is wet or dry.本發明提供用於確定噴霧器之霧化元件係乾之各種配置。可利用自第一頻率掃描至第二頻率之電信號驅動該噴霧器之可振動元件。在利用自該第一頻率掃描至該第二頻率之該電信號驅動該噴霧器之該可振動元件時,可量測該噴霧器之該可振動元件之阻抗值序列。可分析該噴霧器之該可振動元件之該阻抗值序列以確定該噴霧器之該霧化元件係濕或乾。100‧‧‧噴霧器200‧‧‧與噴霧器耦聯之噴霧器控制模組之實施例210‧‧‧控制模組211‧‧‧處理器212‧‧‧非暫態電腦可讀儲存媒體213‧‧‧電信號輸出模組215‧‧‧電壓供應230‧‧‧導線
