Abstract
A temperature monitoring system includes a device for monitoring temperature over a period of time, an adaptor in communication with the temperature monitoring device (TMD) and a data programming device (DPD) in communication with the adaptor. The TMD includes a temperature sensor, a central processing unit (CPU) electrically connected to the temperature sensor, and a power source for continuously supplying power to the CPU. The CPU includes volatile memory into which measurements made by the temperature sensor are stored, the volatile memory in the CPU serving as the sole memory device in the TMD. The TMD is free of means for suspending power from the power source to the CPU. In use, each successive measurement taken by the temperature sensor overwrites the previous measurement stored into the CPU volatile memory. In this manner, the TMD stores no historical data throughout its monitoring process.
