Polymerase Chain Reaction (PCR) is an amplification method of genetic materials and is
used in almost every process that includes genetic material treatment. Conventional PCR
machines control the process with a computer that is connected with a wire, limiting the
mobility and requiring an expensive, high technological installation skill. This paper utilizes
the wireless Bluetooth technology to resolve such problems, enabling the user to control the
PCR process with a smartphone. The PCR machine is paired with a smartphone, and a
protocol that can control the PCR machine is integrated in the smart phone. By controlling
the PCR machine with a smartphone many advantages can be achieved from enabling PCR
machines to be installed in an environment that does not provide wired networking, reduce
the cost and improvement in convenience of control and mobility.
