Abstract
Described is a device for diffusing volatile substances. The device includes a container for holding a liquid containing the volatile substances, a piezoelectric element, the vibration of which causes the diffusion of the volatile substances, and a control electronics that applies an electrical signal to the piezoelectric element, adjusting it to operate at its resonance frequency. The control electronics searches for the resonance frequency and analyses the electrical signal to determine whether or not the liquid is present in the container based on that resonance frequency.
