Abstract
A device includes an antenna configured to be disposed within a cavity of an appliance. The appliance includes an electrode and the antenna includes a sheet of conductive material having a surface area that is equal to or greater than a surface area of the electrode. The device includes a voltage sensor coupled to the antenna, an output device, and a controller coupled to the voltage sensor and the output device. The controller is configured to generate an output at the output device. The output is determined by a voltage of the antenna.
Claims20
A device configured to be positioned entirely within a heating cavity of a heating appliance, wherein the heating appliance includes an electrode configured to emit radio frequency energy into the heating cavity, the device comprising:
- a housing sized to fit within the heating cavity, wherein the housing is not permeable to the radio frequency energy emitted by the electrode, and the housing is permeable to transmissions to or from a wireless communication system;
- an antenna coupled to and positioned outside of the housing;
- a voltage sensor coupled to the antenna;
- the wireless communication system enclosed within the housing;
- and
- a controller enclosed within the housing and coupled to the voltage sensor and the wireless communication system, the controller being configured to:
- receive a first voltage measurement from the voltage sensor, and
- transmit, using the wireless communication system, an indication of the first voltage measurement to a remote computer system.
