Connected objects and the Internet of Things (IoT) are spreading gradually in all areas of daily life: transport, industry and the field of health and well-being. IoT has completely revolutionized the health sector through a continuous chain of diagnostics, treatments and omnipresent follow-ups. The watches and bracelets connected are one of its applications in this area that dress more and more our wrists. Connected wristbands are gradually entering the field of health thanks to their interest. Different models are designed by several companies and intended for different categories of users. The goal of this project is to design a connected bracelet that helps the user to improve their well-being and preserve their health while ensuring ease of use. From the technical point of view, the system measures and tracks physical activity (number of steps, number of calories burned and distance travelled), vital constants (heart rate and body temperature) and ambient temperature in real time. It allows sending alerts by SMS with the location of the person, in case of a fall as well as in case of anomaly in the pulse or the body temperature. If the option of alerts is activated and it displays the necessary information in case of emergency via the Android application, after scanning the QR code on the wristband. The connected bracelet is built around the microcontroller of the development board ESP8266 that provides system management, acquisition and processing of data retrieved by the various sensors as well as sends them to the Android application via Wi-Fi. Android application receives data sent by the ESP8266 using the TCP/IP protocol between a server and a client, the latter provides several functions such as processing and data backup sends SMS alerts and the display.
