The Concept: To design a wearable heart rate monitor using photoplethysmography that will alert specific individuals if the wearer's heart rate goes below or above a pre-defined threshold. It should also allow for remote monitoring of the wearers pulse at any given time. The schema: the electronic system is a schema of wearable device which controls pulse quite precisely in a few minutes. The device utilizes the signals from human body to detect the occurrence of heart beat. As soon as the device detects the critical value, it transmits a coded signal. The signal is decoded by a GSM receiver to produce control signals for switching an alarm device as mobile messaging device and trigger a emergency with wherever SIM.
