STORAGE SYSTEM

摘要

A storage system (500) comprises a storage unit (100), wherein said storage unit (100) has sites (S1a, S1b) for accommodating two or more of said objects (G1), said storage unit (100) further comprising one or more capacitive proximity sensors (50) arranged to detect the presence of said objects (G1) in the vicinity of said sites (S1a, S1b). The storage unit may be e.g. a shelving in a retail store. The filling ratio (N/Nmax) or the number (N) of objects on the shelves (90) may be monitored in real time. Consequently, out-of-shelf situations may be effectively avoided.
