The document describes a vehicle accident detection system that uses piezoelectric sensors to detect vibrations during an accident. When an accident is detected, an Arduino microcontroller connected to the sensors triggers a GSM module to send notification messages to authorized users. It also triggers a buzzer to alert people nearby. The system is intended to help reduce the number of deaths from road accidents.
Vehicle accident detection and messaging system using GSM and arduino
- 2. MOTIVATION About 1.24 million people die each year as a result of road traffic crashes. Without action, road traffic crashes are predicted to result in the deaths of around 1.9 million people annually by 2020. Decade of Action for Road Safety (2011–2020) with the aim of saving millions of lives by improving the safety of roads, vehicles and improving emergency services. VehicleAccidentDetectionSystem 2

- 7. RELAY A relay is a simple electromechanical switch made up of an electromagnet and a set of contacts. Relays are found hidden in all sorts of devices. In fact, some of the first computers ever built used relays to implement Boolean gates. VehicleAccidentDetectionSystem 7
- 8. PIEZO ELECTRIC SENSOR A piezoelectric sensor is a device that uses the piezoelectric effect, to measure changes in pressure, acceleration, temperature, strain or force by converting them to an electrical charge. When accident occurs, Piezo electric sensor detects the vibrations based on the vibrations GSM module sends messages to the authorized users. VehicleAccidentDetectionSystem 8
- 9. GSM MODULE GSM module is interfaced to Arduino module Serially. AT commands are used to send messages from GSM module to the authorized users. GSM TX pin is connected to Arduino RX pin. GSM RX pin is connected to Arduino TX pin. VehicleAccidentDetectionSystem 9
