Smart Tire Pressure Monitoring & Emergency Alert System Using IoT

Vehicle safety is a major challenge, and tire pressure monitoring is essential for preventing accidents caused by underinflated or overinflated tires. This work proposes an automated Smart Tire Pressure Monitoring System (TPMS) that uses pressure sensors, a vibration sensor, GSM, GPS, and IoT to monitor tire pressure and temperature in real time. The device includes an Arduino microcontroller that continuously tracks tire conditions and sends notifications when irregularities are detected. When a tire bursts or there are other issues, GPS tracking helps locate the car, and a GSM module notifies the car caretaker of the situation. Along with a smartphone application that suggests local puncture repair shops, the device also has an OLED display for real-time information. In addition, a temperature sensor detects excessive heat in the tire, lowering the risk of fire cause by friction. By providing real-time notifications, automated emergency response, and remote monitoring through cloud connectivity, this IoT-based TPMS improves road safety. By providing intelligent tire health management, automated vehicle speed adjustments, and instant notifications, the suggested solution performs better than existing methods and guarantees a safer driving experience.
