Abstract

Car battery theft is still a major security threat to people, especially those with standard alarm systems, which are useless after the disconnection of the battery from the vehicle. This study proposes a low-cost car battery theft prevention system based on GSM that can sense battery removal and inform the vehicle owner in real time via an Arduino Nano microcontroller, a SIM800L GSM module, an ESP8266 Wi-Fi module, a sensing circuit relying on a relay, and a buck converter to regulate the voltage. The relay constantly observes the line continuity of the battery, and in the case of battery disconnection, SMS and call signals are sent to the subscribing user. Testing was performed based on experimental testing in normal connection, disconnection of the wire, and power fluctuations. The proposed solution is credible, affordable, and applicable to real-world vehicle security applications that do not require Internet connectivity.
