Abstract
Various embodiments of devices and methods for indicating the level or amount of a vaporizable material in a dispenser, such as an air freshener device or insect control system, are disclosed. An embodiment of a dispenser includes a housing with a reservoir and wick that may be removably coupled to the housing. A circuit within the dispenser measures a property in the wick, such as an electrical property, or a level of vaporizable material in the reservoir and triggers an indicator that provides a visual or audible signal to the user advising that the reservoir is low or empty.
