IoT-Based Personal Safety Band

Personal safety is a crucial factor in emergency situations, accidents, and situations in which immediate help is needed. In such situations, it may be impossible for someone to make a phone call and inform their family members or emergency contacts. This study presents an IoT-based personal safety band for immediate emergency assistance using an embedded wearable device. This system features a main microcontroller (ESP32). It features an MPU6050 accelerometer/gyroscope to detect any abrupt, unusual, or potential fall situations. There is also a manual SOS button for the user to immediately trigger the emergency alert. If an emergency situation is detected, the user location will be obtained via the NEO-6M module and the emergency alert with user location will be sent to registered contacts via the SIM800L module. Local emergency alerts are given via the buzzer and LED. The safety band is designed to be portable, light weight and can be worn by a variety of users. Including women, elderly and children. The system helps reduce the time taken to obtain emergency assistance.
