A thermal sensing device including a plurality of sensors with at least one of an infrared sensor for capturing infrared data from a biological subject and an imaging sensor for capturing a thermal image of the biological subject. The device includes a display for providing a diagnostic output about the biological subject. Further, a processor operably connected for computer communication with the plurality of sensors and the display identifies at least one feature in the thermal image using a machine learning process, determines the diagnostic output based on the infrared data corresponding to the at least one feature, controls the display to provide the diagnostic output.
