Delimitations

Delimitations

• Research will not include the lifespan and structure of the microcontroller and integrated circuits, information related to such may be observed on an individual manufacturer's datasheet.

• The research will not include the addition for more the three storage units due to: this observation that the microcontroller would restrict the addition of more storage units, due to microcontroller IO pin count. Information related to such may be observed on an individual manufacturer's datasheet.

• The research will not include the storage unit: access time duration and space allocations per shopper, due to the supermarket-parcel counter operational constraints.

• The research will not include the calibration of weight sensor due to an issue: That the weight of a parcel placed in a storage unit, may throw off the weight sensor detection; this include small items weighing under the sensors detection range; the sensor may perceive that there is no object is placed on the storage unit, this is due to manufacturer's calibration range.

• The research will not include the development of a 12V power supply and the power outage plan.
