Monitoring environmental conditions of storage units for vaccines and other climate sensitive products

An environmental monitoring device for monitoring one or more environmental conditions, the device comprising:

• a main printed circuit board (PCB) having a modular configuration including an expansion port/connector and capable of supporting a display module;
• and
• a short-range wireless communication interface disposed on the main PCB, the short-range wireless communication interface comprising a BLUETOOTH Low Energy (BLE) radio and being configured to establish a short-range wireless communication link with at least one other environmental monitoring device;
• and
• a plurality of different physically interchangeable communication modules implemented as daughter boards that are selectively connectible one-at-a-time with the expansion port/connector of the main PCB, each communication module implementing a different long-range wireless protocol;
• wherein:
• selective connection of a given one of the communication modules configures the device for wireless communication according to the corresponding long-range protocol;
• the device includes an on-device user interface and is operable to initiate, via on-screen navigation, a server-less cloning operation in which a configuration dataset comprising one or more alarm thresholds, allowable ranges, logging and/or transmit intervals, and network settings is transmitted from the device to the at least one other environmental monitoring device over the BLE link and applied at the other environmental monitoring device without reliance on an external server;
• and
• the device is configured to sense, locally store, and report environmental data including at least temperature and/or humidity, and to generate a user-acknowledgeable alarm when a sensed condition is outside a user-defined allowable range.
