The present paper reports an emergency accident alarming system. This project aims to intellectually build a sensor circuit using Arduino Uno Microcontroller which can be easily installable in every vehicle. This device provides an immediate accident emergency system of protocol using the various sensors embedded such as Accelerometer, GPS module, GSM module in collaboration on the Arduino Uno board. Upon accident detection, the GSM module facilitates immediate communication with various emergency services like Ambulance Services, Hospitals, Fire-Station, Registered-Relatives providing them with crucial information such as exact location of accident and severity of the incident. Focusing on the ambulance services the project is entitled as Alarm-Bulance.
