Detailed Description

Sensor data record stored as one element in the flash circular queue.

New sensor readings are appended at the tail; when the queue is full the oldest records are silently overwritten (circular / ring-buffer behaviour). The total size of one record is fixed at SZ_DATABLOCK bytes; changing the set of active sensors changes this size and forces a memory reset.
