Abstract

An infrared (IR) temperature sensor includes a detector element, a wireless communication element, a memory, and a processor. The detector element detects IR radiation emitted from an object and generates an electrical signal proportional to the detected IR radiation. The memory is configured to store command instructions. The processor is operably connected to the detector element, the wireless communication element, and the memory. The processor is configured to execute the command instructions to transform the electrical signal into an output signal proportional to a temperature of the object and transmit the output signal with the wireless communication element. The IR sensor further includes a body that encloses the detector element, the wireless communication element, the memory, and the processor. The body defines an aperture that extends between the detector element and a mounting surface of the body and faces the object.
