Smart Dispensing of Ingredients Using VL53LOX and Piezoelectric Polymer Sensor

This paper describes smart dispenser system for automatically dispensing the ingredients for cooking machine using VL53LOX sensor on the cap of the dispensing jar and a piezoelectric polymer gasket sheet at the bottom. The combination of these two sensors enable calibrate itself and provide accurate quantity of dispensing which is very much essential in certain process. Piezoelectric polymer sensor at the bottom and VL53LOX sensor on the cap communicate the data using IoT. VL53LOX sensor provides the level of the ingredients present. Piezoelectric polymer gasket sensor provides change in resistance value as the quantity varies in the container. By sensor data fusion, an AI engine predicts the exact volume dispensed. The containers periodically “wake up” and communicate to a base station regarding their inventory status and dispensed quantities, and the fill status is automatically updated using the same sensor (Shivraj et al. in Int Res J Eng Technol (IRJET) 06(06), 2019 [1], Voyles and Bae in Smart tupperware1: an example of bluetooth wireless sensor networks for human assistive mechatronic systems [2]). The volume is displayed by graphical user interface using geometrical parameters of the container based on user requirements, and a mobile app gives simulation of the quantity on your mobile screen.
