Smart Car Accident & Alcohol Detector Using ESP32

Smart Car Accident & Alcohol Detector Using ESP32

Consistently the existence of roughly 1.3 million individuals is cut short because of road traffic crashes. Somewhere in the range of 20 and 50 million additional individuals experience non-fatal injuries, with many causing a disability because of their physical issues.

Road traffic injuries make high economic losses for people, their families, and to countries in general. These misfortunes emerge from the expense of treatment as well as lost efficiency for those killed or crippled by their injuries, and for family individuals who need to get some much-needed rest work, or school to really focus on the harmed. Road traffic crashes cost most nations 3% of their GDP.

So here we design a system that can alert the vehicle owner/loved ones over the Blynk 2.0 mobile or web application as soon as any signs of an accident or may lead to an accident are detected. As well as the system stores all readings that lead to and happened during the accident so that investigators may study the exact causes of the accident to avoid further such instances.

This System provides the following advantages:

· Instant data Capture from Sensors

· Instant alert for Drunk Driving Detection

· Instant alert for Fire or Accident Detection

The system makes use of a Temperature sensor for fire detection in the car, a Vibration sensor to detect any impact force or heavy vibrations, an Alcohol sensor to check if the driver was drunk, a gyro scope sensor to record data if the vehicle tilted or turned over during accident and a GPS send data to Blynk app with GPS Coordinates about the incident. This complete system is now powered by an ESP32 to operate the system.

The system also has 2 Motors used to demonstrate a car engine. We can increase the speed of Motors using Trimpot. As we increase the speed beyond the set limit, the system detects overspeeding and sends an update with over speeding alert and GPS coordinates to the registered number.

The system monitors all sensor data to check for any abnormalities. If the fire sensor detects a fire, the controller operates the interfaced to send an update to the Blynk application informing about the event and also starts recording data.

Similarly, if the vibration sensor detects heavy vibrations, the controller sends the data to the Blynk app informing about the event. If the alcohol sensor is triggered the controller similarly sends an alert to the Blynk app with alcohol data and GPS Coordinates on the Map link for easy vehicle location tracking.
