Emergency Safety Device

Abstract: Women’s safety is an important issue that demands practical and reliable technological support. This paper presents a review and development of a women safety band that uses Arduino Nano, SIM800L GSM module, and NEO-6M GPS module to provide quick emergency communication and real-time location sharing. The system operates in two modes: emergency and safe. In an emergency, pressing the alert button sends the user’s current GPS coordinates with a Google Maps link to predefined guardian contacts and automatically makes a phone call to the first number. In safe mode, a message is sent to confirm the user’s safety. The compact and wearable design allows easy operation while ensuring immediate help in critical situations. The device offers a cost-effective and efficient way to enhance women’s safety through the use of embedded systems, GSM, and GPS technologies. Future improvements can include silent vibration alerts, a buzzer alarm, and mobile application integration for advanced functionality.
