Abstract

This paper describes the implementation of the Zapper with microcontroller to meat products to prove that it can significantly decrease E. coli bacteria. The Hulda Clark Zapper, individually produces an output of positive offset voltage and is basically used for curing sicknesses in humans. A load cell sensor was used to get the input weight and an instrumentation amplifier AD620 was used to amplify the signal of the load cell. The load cell output will correspond to a designated weight input that is programmed in the microcontroller. The PIC16F877A microcontroller was used to vary the input power, with the help of relays, relay drivers, and voltage regulators of the zapper. The two types of testing, namely Quantitative Polymerase Chain Reaction (QPCR) for the microscopy testing and Fluorescence spectroscopy, were used to prove the bacteria killing that both produced excellent results in terms of bacteria elimination.
