GPS BASED ANTI-THEFT VEHICLE ALERT & ENGINE LOCK SYSTEM USING NODE MCU

This study of increasing incidents of vehicle theft demand intelligent and real-time security solutions.This paper presents the design and performance of a GPS-based anti-theft vehicle alert and engine lock system using Node MCU (ESP32).The system continuously monitors the vehicle ignition status and detects unofficial access.Upon detection, it sends real-time location details to the vehicle owner via GSM conversation.The ESP32 microcontroller processes GPS and GSM data and enables remote engine locking through a relay control mechanism, preventing vehicle motion.An LCD display and buzzer provide local alerts during theft condition.The proposed system offers a cost-effective, reliable, and efficient solution for enhancing vehicle security with real-time tracking and remote immobilization facility.
