A smart device for the promotion of shelf products exhibited in consumer commercial settings may utilize sound, motion, light, and smell when a consumer is proximate a shelf. The smart may consist of a motion transmission system (T) installed in a box (1), a modular universal gripping system (32), an integrated electronic circuit board (35) on which control and command components are installed; an electronically controlled magnet lamp (24), a smell dispenser (28), an audio system (A) consisting of a loudspeaker (34) and an audio amplifier (37), a motion sensor (29), and communication means (C) for bidirectional transmission/reception of the commands for operation parameters. Operation parameters may be keyed to a consumer's characteristics, reports on the traffic in front of the shelf where the device is installed, and the number of interactions with the consumer. This information may be uploaded on the web platform and provided as a report.
