How It Works

The Women Safety Device with GPS Tracking and Alerts using Arduino functions as a portable, wearable emergency system designed to transmit distress signals automatically or manually. At the heart of the circuit is an Arduino Nano, which continuously processes data from multiple connected modules. When the user presses the panic button or triggers the 433 MHz RF transmitter, the system initiates an emergency protocol. Simultaneously, the NEO6M GPS module locks onto satellite signals to determine the user's precise geographical latitude and longitude coordinates. Once the location data is acquired, the Arduino interfaces with the SIM900 GSM modem using serial communication libraries (like SoftwareSerial and TinyGPSPlus) to compose and dispatch an SMS text message containing the live location link to preset emergency contacts. Additionally, an onboard buzzer activates to draw immediate attention from people nearby during a distress situation, providing both an audible alarm and a remote digital notification.

Why Build This

Frequently Asked Questions

Why does the SIM900 GSM module need a separate or stable power supply?

GSM modules draw significant peak current when searching for a cellular network or transmitting data, which can cause the Arduino's onboard regulator to brown out and reset the system if power is unstable.

Can the NEO6M GPS module get a location fix indoors?

GPS modules generally require a clear line of sight to the open sky to lock onto satellite signals, so initial testing and location acquisition should be performed outdoors or near a window.

What is the purpose of the 433 MHz RF transmitter and receiver if there is already a button?

The RF modules allow the safety device to feature a wireless trigger mechanism, enabling the user to wear a small panic button separate from the main processing unit.
