A　healthy　human　life　is　the　top　priority　of　every　humanbeing　in　the　present　era.　In　a　world　full　of　high-tech　markets,　where　everyday　a　new　technology　is　introduced　to　solve　prevailing　world　problems　in　a　more　efficient　way.　We　must　find　out　some　course　of　actions　to　save　as　many　human　lives　as　possible.　Therefore,　this　research　is　related　to　Internet　of　Things　(IoT).　A　sensors　based　mobile　application　that　has　the　capability　to　detect　heart　rate;　where　the　detected　pulse　rate　are　imputed　into　the　system　that　performs　some　computations　to　decide　whether　the　human　is　in　a　normal　state　or　needs　certain　medical　assistance.　The　primary　motivation　behind　this　research　is　to　comparatively　analyze　different　existing　technologies　and　to　develop　an　application　that　can　build　a　strong　research　background　to　aid　researchers　in　the　establishment　of　an　early　heart　attack　detection　and　prevention　system.　©　2020　IEEE.
