It is known that many individuals suffer from chronic diseases such as heart disease, high blood pressure, and sleep apnea, which requires constant monitoring, which is only found in the hospital, and the high cost that the individual cannot afford, especially at present. This paper proposes a system through which an individual can monitor vital signs and can use the wearable device by himself without the need for assistance. Wearable devices have been used from the sensors where the proposed system uses six sensors which are the electrocardiogram, the pulse oximeter, heart rate, blood pressure, skin temperature, temperature, and humidity as it collects data and then transfers it via Wi-Fi to the microcontroller on the Internet of things. The results of the sensors have been successfully obtained. Finally, linked them to the Blynk platform that displays the desired results for the individual.
