Abstract: A detection device for time and temperature tracking includes a signal processing unit in operable communication with a memory, a temperature sensor, a timer, and a display window. The detection device displays, via the display window, a first label.. The detection device detects, by the temperature sensor, a first temperature. The detection device determines, by the signal processing unit, a first temperature excursion, where the first temperature exceeds a first threshold. Responsive to determining the first temperature excursion, the detection device starts the timer configured to expire after a first duration of time. The detection device detects, by the temperature sensor, a second temperature. Responsive to either (1) the timer expiring after the first duration of time; or (2) determining, by the signal processing unit, a second temperature excursion, where the second temperature exceeds a second threshold, the detection device displays, via the display window, a second label.
