Abstract
An air treatment device having electrodes supported by a housing and a voltage generator operatively coupled to the electrodes. The air treatment device includes at least one sensor operatively coupled to the voltage generator for sensing a condition and providing signals used for adjusting the voltage generated by the voltage generator.
Claims20
An air treatment device comprising:
- a housing;
- a plurality of electrodes supported by the housing;
- a voltage generator operatively coupled to the electrodes, the voltage generator being operable to generate voltage;
- at least one sensor operatively coupled to the voltage generator, the sensor having a light source and a light detector, the voltage generated by the voltage generator being adjusted based on a condition sensed by the sensor;
- and
- a processor operatively coupled to the sensor and the voltage generator, the processor being operable to cause an adjustment of the voltage based on a signal received from the sensor, the signal being related to the condition sensed by the sensor.
