PROBLEM TO BE SOLVED: To provide a weight monitoring apparatus capable of responding easily to displacements of and changes in the arrangement and shape of an object to be weight-monitored. SOLUTION: In the apparatus, a plurality of sensor units 1-1 to 1-8 intermittently transmit weight data and identification data using a wireless way, and a repeater device 10 receives the weight data and the identification data and sends them to a processing device, and the processing device 20 collects the data from the repeater device 10 and computes weight values corresponding to groups on basis of the total value of the weight data corresponding to one or more identification data being registered as the same group. Since it becomes unnecessary to carry out wiring cables between the sensor units 1-1 to 1-8 and the repeater device 10 or the processing device 20, the weight monitoring apparatus can respond easily to changes in buying / selling commercial goods and in models in a display case which are frequently varied.
