Abstract
A temperature control system includes an integrated circuit that combines magnetic sensitive elements and infrared sensors to detect user temperature settings and measure temperature, respectively. Integration of the various sensors results in a very cost-effective and reliable temperature control system suitable for consumer applications.
Claims9
