Built using Python and ML libraries like Scikit-learn and Pandas, the system uses algorithms like Linear Regression or Random Forest to predict future prices. Users can input property details, and the system outputs an estimated market value.
Advanced versions may include geolocation data, trend analysis, and visual dashboards for deeper insights. The platform can be integrated into a web application using Flask or Django, making it accessible and user-friendly.
This predictive system is valuable for understanding real estate trends, planning investments, and gaining a competitive edge in the property market.
IOT Based Alcohol Detector and Engine Lock system using Arduino

IOT Based Alcohol Detector and Engine Lock system using Arduino
This project aims to design an IoT-based alcohol detection system integrated with an engine lock mechanism using an Arduino microcontroller. The system uses an MQ-3 gas sensor to detect alcohol presence in the driver’s breath. If alcohol is detected beyond a preset threshold, the system activates a relay to lock the engine, preventing the vehicle from starting.
An ESP8266 Wi-Fi module is used to send real-time alerts to a cloud server or mobile app, enabling remote monitoring. The solution enhances vehicle safety by ensuring that only sober individuals can operate the vehicle, helping reduce accidents due to drunk driving.
This smart system is cost-effective, easy to implement, and ideal for personal cars, commercial fleets, and public transport vehicles.
