Alcohol Detector and Recorder for Auto Accidents

 Alcohol Detector and Recorder for Auto Accidents

Approximately 1.3 million people have their lives end every year as a result of a traffic accident. An additional 20 to 50 million people suffer non-fatal injuries, with many of them leading to disabilities as a result of their physical condition.

High economic damages are caused by road accidents for victims, their families, and nations at large. These disasters result from the cost of medical care, lost productivity for those who die or become disabled as a result of their injuries, and time away from work or school for family members who need to obtain some much-needed rest in order to properly care for the injured. Most countries incur a 3% GDP loss as a result of traffic accidents.

As a result, we have created a system that may send an SMS to the owner of the vehicle and their loved ones whenever any signals that an accident may occur are found. Additionally, the system records all readings that preceded and occurred during the accident so that investigators may determine the precise causes of accident and prevent similar occurrences in the future.

The advantages that this system offers are as follows:

• Immediate data collection from sensors

• Instant SMS alert for Drunk Driving Detection

• Instant SMS Alert for Fire or Accident Detection

• Accident Data Storage for Investigation

The system uses a temperature sensor to detect a fire in the car, a vibration sensor to detect impacts or strong vibrations, an alcohol sensor to determine whether the driver was intoxicated, a gyroscope sensor to record data if the vehicle tilted or turned over during the accident, and a GPS and GSM modem to send an SMS with GPS coordinates about the incident. An Arduino Mega is now used to power the entire system in order to run it.

Additionally, the device features 2 motors that are utilised to simulate an automobile engine. Trimpot allows us to increase the speed of the motors. As we exceed the predetermined speed limit, the system detects overspeeding and sends an SMS message to the registered phone with an overspeeding alert and GPS data.

All sensor data is monitored by the system to look for any anomalies. When a fire is detected, the controller activates the connected GSM modem to send an SMS alerting the registered contact number of the event and begins data collection.

Similar to this, if the vibration sensor picks up strong vibrations, the controller sends an SMS to the registered phone telling the user about the incident. When the alcohol sensor is activated, the controller sends an SMS notice with alcohol information and a link to a map with GPS coordinates for simple car location monitoring.

The black box begins collecting all sensor data on a second-by-second basis in an SD card in the event that any sensor detects aberrant activity. This allows the investigative team to retrieve the data and determine exactly what happened during the accident.
