vehicle accident detection and messaging system using gsm and arduino
TRANSCRIPT
VEHICLE ACCIDENT
DETECTION SYSTEM
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.

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.

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.
