Oxy Shield is a child safety system developed to reduce the risk of unsafe air conditions inside closed vehicles. When a child is left inside a parked car, carbon dioxide levels can increase rapidly and become dangerous. The system uses an ESP32 microcontroller and a CO2 sensor to monitor air quality in real time. If the level exceeds a safe limit, a servo motor automatically opens the car window to allow fresh air. A buzzer and RGB LED alert nearby people, while instant notifications are sent to the owner through Telegram and monitored using the Blynk app for added safety.
