This project implements an SOS call system using Arduino UNO. It is designed to send an emergency distress signal (SOS) to predefined contacts when activated. This can be a crucial safety feature in situations where immediate help is required.
Architecture of the circuit
clone the repo
git clone https://github.com/amandeepsirohi/SOS-Call-Based-System.git
- Arduino board (e.g., Arduino Uno)
- GSM module (e.g., SIM900)
- GPS module (optional, for location tracking)
- Push button or trigger sensor
- Power source (battery or power supply)
- SIM card with active plan
- Required connectors and cables
- Connect the GSM module to the Arduino using appropriate pins (TX, RX, VCC, GND).
- Connect the GPS module in a similar fashion if used.
- Wire the push button to an Arduino pin for activation.
- Connect all the components according to the wiring diagram.
- Insert a valid SIM card into the GSM module.
- Load the provided Arduino sketch onto the board using the Arduino IDE.
- Ensure that the GSM and GPS modules are powered up and properly connected.
- Upload the code to the Arduino.
- Power up the Arduino with the required power source.
- Press the push button to trigger the SOS call.
- The GSM module will establish a connection and send an SOS message to predefined contacts.
- Optionally, if a GPS module is connected, the location coordinates can be included in the SOS message.
