Vehicle Accident detection System using arduino and GSM

1. VEHICLE ACCIDENT
DETECTION SYSTEM

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.

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.

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.

 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.
