IoT Hajj and Umrah pilgrim movement with heart rate tracker

In this paper, a smart tracking prototype and a health monitoring system for Hajj and Umrah pilgrims have been developed. The prototype is using the TTGO T-watch with GSM/GPS module and a pulse sensor. The system collects the data from the GPS module pulse sensor on the smartwatch to determine the pilgrims’ location (longitude and latitude) and heart rate. The watch’s data is sent to the Blynk server and then shown in the application called ’iTrack’, built using the Blynk platform. It will show the live location and current heart rate of the pilgrims. This device will notify the travel agent and pilgrim when the heart rate is beyond the acceptance range (below 40 bpm or above 128 bpm). The watch’s GSM module makes the device a stand-alone watch and provides the watch with mobile data. The internet is used to send data to the application. The notification is sent to the registered number using SMS. This prototype also has a call button that will call the registered number once being pressed. In conclusion, this prototype is easy to set up and used to help the travel agency and group members monitor the pilgrim’s whereabouts and heart rate.
