A Project Report in Partial Fulfilment of the Requirements for the Degree of Master’s in Embedded and Mobile Systems of the Nelson Mandela African Institution of Science and Technology
Tanzania is among the East African Countries with rapid economic development, and it is a
low middle-income country. The development of industries is among the factors that contribute
to the economic growth of the country. Tanzania has been developing beverages industries;
however, these industries are facing a number of challenges including poor monitoring of tanks
during liquid pumping from boiler tank to dilution process. This problem resulted in spilling
fluids, tampered wine tests, and industrial accidents. The purpose of this project wasto develop
a system that can be able to monitor juice level within the tanks and regulate the pump using
voice commands through Alexa echo dot. The pump in this system was controlled by voice
commands, and an ultrasonic sensor was used to sense the juice level in the tank and send data
to a microcontroller, which processed the data and displayed the juice level on a Liquid Crystal
Display (LCD). Once the juice level reached a threshold level, the pump was automatically
turned off. The developed system successfully stopped overflows, accidents, and changes in
juice flavor during the dilution process, according to major findings from testing and validation
of the developed system. Existing way, however, are manual methodology, on the other hand,
are not interactive and are costly. The developed system also caters to the physically impaired
person, allowing them to engage in tank monitoring without difficulties. The system was
created for Raha Beverage Company Limited located in Arusha, Tanzania.
