The　purpose　of　this　paper　is　to　design　and　manufacture　a　microfluidic　PCR　chip,　and　construct　an　embedded　platform　for　realizing　temperature　control　in　chip　PCR　reaction.　Based　on　idea　of　modular　design,　hardware　is　divided　into　the　implementation　of　temperature　control　data　sampling,　heating　drive　the　temperature　control　function.　Software　platform　mainly　contains　the　embedded　operating　system　based　on　the　hardware　platform,　the　temperature　monitoring　and　client　software　running　on　Windows.　Temperature　monitoring　and　PCR　experiments　are　performed　to　verify　the　design.　The　results　show　that　the　system　can　meet　the　micro-PCR　microfluidic　chip　temperature　control　requirements,　to　achieve　the　precise　temperature　control　and　remote　monitoring.　©　euspen　Headquarters.
