Smart Auto Cutoff Charger or Socket

The Smart Auto Cutoff Charger or Socket project addresses the common issue of electronic device overcharging, which can lead to battery degradation, overheating, reduced efficiency, and safety risks. The system employs a microcontroller (Arduino or ESP32) paired with voltage and current sensors (INA219 or ACS712) to monitor the charging process in real time. A relay module regulates the power supply, automatically cutting off charging based on preset voltage and current thresholds to prevent overcharging. A built-in display (LCD or OLED) provides live feedback on the charging status. Key safety features include overcharge protection, short-circuit detection, and customizable thresholds. Future enhancements envision IoT integration for remote monitoring and control via mobile applications, temperature-based cutoffs, energy usage tracking, and timer-based charging. Designed for a wide range of battery-powered devices such as smartphones, laptops, and power banks, the system optimizes charging cycles, enhances safety, and extends battery life, making it suitable for smart homes and modern IoT environments.
