The project aims at developing a TPMS (Tire Pressure Monitoring System), which displays the tire pressure on a smart phone. The proposed system provides the facility of dynamically changing the tire pressure limit setting. Also, the system alerts the driver by horning alarm if the tire pressure is high or low.   Tire Pressure Monitoring Systems (TPMS) are a new standard for improved vehicle safety. These systems are an important and growing safety feature in newer vehicles. The proposed system utilizes advanced integration techniques to provide a TPMS solution that provides real-time tire pressure monitoring and alerts the driver to improperly inflated tires.     The controlling device system of the whole systems is a Microcontroller. Pressure sensor, Wi-Fi module, Buzzer is interfaced to the microcontroller. The microcontroller continuously read the data from pressure sensor. When the tire pressure is high or low, the microcontroller gives the alert through buzzer and sends them to the user mobile phone through WI-FI. This system is capable of alerting in case of improper inflated tires. The provision of dynamic pressure setting is available in the car system. Microcontroller is loaded with an intelligent program written in embedded ‘C’ language to perform the task.    

The objectives of the project include:  

1. Dynamic tire pressure setting.
2. Usage of wireless IOT technology.
3. Continuous monitoring of tire pressure on mobile phone through WI-FI.
4. Alerts of improper inflated tires.
