Built using an IndusBoard Coin, it addresses the urgent need for immediate assistance, particularly for the elderly, children, and those with medical conditions.

The device integrates a MEMS sensor for fall detection, a temperature sensor for health monitoring, and GPS and GSM modules for location tracking and communication. Automatic and manual response capabilities enhance its effectiveness. The MEMS sensor identifies falls or sudden movements, sending alerts with GPS coordinates and sensor data to emergency contacts via SMS. The temperature sensor triggers alerts for abnormal readings, potentially indicating a health crisis. An emergency button allows manual alert activation, ensuring user control in critical situations.

The GSM module ensures alerts are delivered via SMS even in areas without internet connectivity, making it suitable for remote and outdoor locations. Despite dependencies on GSM network coverage and battery life, the device represents a significant advancement in personal safety. Future iterations could incorporate additional sensors, wearable designs, and a mobile app for real-time tracking and control.

Harnessing advanced sensor and communication technologies, this device delivers a vital layer of security. Fig. 1 shows the prototype, Fig. 2 illustrates the block diagram, and required components are detailed in the Bill of Materials table.
