Overview

Safe Sense consists of four easy-to-install sensors that provide both audio and visual feedback for objects in proximity to your vehicle. This system enhances safety by addressing critical issues such as blind spot detection, parking assistance, and collision prevention.

Key Features

• Blind Spot Navigation: Real-time alerts for objects in your vehicle's blind spots
• Parking Assistance: Visual and audio guidance for tight parking spaces
• Collision Prevention: Advanced algorithms predict potential collisions 3-5 seconds before they occur
• Accident Analysis: Detailed collision reports including time of impact, vehicle speeds, and suggested at-fault determinations
• Universal Compatibility: Designed to work with any vehicle, regardless of make or model
• User-Friendly Installation: Simple enough for anyone to install, including non-technical users

The Problem We're Solving

In the United States alone, there are approximately 242,000 side-swipe accidents annually, resulting in over 2,500 fatalities and 27,000 injuries. Moreover, about 62% of vehicles on the road are models from before 2015, lacking Advanced Driver Assistance Systems (ADAS). Safe Sense aims to bridge this safety gap by providing an affordable, aftermarket solution that brings modern safety features to older vehicles.

How It Works

1. Install four sensors at the corners of your vehicle
2. Download our cross-platform mobile application
3. The app automatically connects to the sensors via Bluetooth
4. Receive real-time alerts and safety information while driving

Technology Stack

Hardware

• Sensors: ESP32 modules with ultrasonic sensors (HCSR04)
• Connectivity: Bluetooth Low Energy
• Power: MT3608 step-up transformer with 3.7v LiPO battery (for wireless version)

Software

• Mobile App: Flutter (iOS and Android compatible)
• Libraries: flutter_ble_plus, geolocator
• Backend: Custom Python 3.9 Flask API

Machine Learning

• Custom model trained on 60 side-swipe accident simulations and 531 AI-generated data points
• Latency: <50ms

Installation

1. Mount the four sensors at each corner of your vehicle
2. Download the Safe Sense mobile app from the App Store or Google Play
3. Follow the in-app instructions to pair the sensors with your smartphone
4. Start driving with enhanced safety features!
