Smart Pilgrim: A Mobile-sensor-cloud Based System To Safeguard Pilgrims Through Smart Environment

Large-scale pilgrimage events often expose participants to harsh environmental conditions, overcrowding, and health risks. To ensure the safety and well-being of pilgrims, this project proposes Smart Pilgrim, a mobile-sensor-cloud-based system that creates an intelligent safety environment using real-time monitoring and communication. An Arduino microcontroller serves as the core unit, interfacing with various sensors such as a pulse oximeter to track vital health parameters, DHT11 to monitor temperature and humidity, a gas sensor for detecting harmful gases, and a MEMS sensor for fall or motion detection. A push button allows for manual SOS alerts, while GPS provides real-time location tracking. In emergencies, the GSM module sends alerts and coordinates to designated contacts or authorities. The system connects to an Android app for live data visualization and interaction. Additionally, a buzzer offers local alerts, and a Zigbee module ensures wireless communication in the absence of mobile networks. This comprehensive safety framework enhances health monitoring, emergency response, and crowd management in pilgrim environments.
