A dispensing device includes a dispenser configured to dispense a volatile material, a sensor configured to detect an environmental condition, and a nonlinear circuit element coupled to the sensor to establish a bias point. A voltage level at the bias point varies nonlinearly with respect to a current that flows through the sensor, wherein the current that flows through the sensor represents the environmental condition. The dispensing device further includes a controller coupled to the bias point. The controller controls the dispenser to dispense the volatile material in response to the environmental condition.
La présente invention concerne un dispositif de distribution qui inclut un distributeur configuré pour délivrer un matériau volatile, un capteur configuré pour détecter une condition environnementale, et un élément de circuit non linéaire raccordé au capteur pour établir un point de polarisation. Un niveau de tension au point de polarisation varie de manière non linéaire par rapport à un courant qui passe à travers le capteur. Ledit courant qui passe à travers le capteur représente la condition environnementale. Le dispositif de distribution inclut en outre un contrôleur raccordé au point de polarisation. Ce contrôleur contrôle le distributeur afin quil distribue le matériau volatile en réponse à la condition environnementale.
