The apparatus comprises a temperature sensor to measure an ambient temperature of the apparatus, a processor configured to control the temperature sensor to periodically measure the ambient temperature to obtain a time-domain series of ambient temperature measurements, and a memory operatively coupled to the processor to record the time-domain series of ambient temperature measurements. The apparatus also comprises a battery coupled to power the temperature sensor, the processor, and the memory, and a communication module operatively coupled to the processor to transmit the recorded time-domain series of ambient temperature measurements to a compliance verification processor. 8629887_1 (GHMatters) P97077.AU.1
