Abstract

A sensor unit for use in a cold chain network is designed to allow rapid replacement of its temperature sensor and related circuitry while preserving the long-term functionality of its primary internal components. The unit features a protective enclosure housing a battery power supply, an internal circuit board with operating hardware and software, and a wireless network interface for communication with a remote monitoring server. An external sensor assembly, mounted to the exterior of the enclosure, includes a temperature sensor and associated circuitry. The external assembly is replaceable without disassembling the enclosure, ensuring minimal downtime and reduced maintenance costs and offering a more efficient and cost-effective solution for cold chain environmental monitoring.
