Story
We have started this effort to assist employees be more efficient. So, first and foremost, we used five components: M5Stack, RGB, I2C Hub, TOF, and RFID. TOF motion is sensed by distance sensing; after it exceeds 200, a red led appears at RGB, indicating that the item is out of stock. When the suppliers load up the supplies and tap into the RFID, it will record who has stocked it up. Smart retail stocks give customers and managers the ability to have visibility over inventory as it moves out of the warehouse as traditional warehouses have trouble keeping track of the records of stock. Retailers provide customers with goods from the manufacturer. Retailers reduce the costs of goods sold for manufacturers.
