Wireless Tire Pressure Monitoring System

Sensor based Tire Pressure Monitoring System for Motor Vehicles is a tire pressure monitoring system used in any type of the vehicles. This technology involves two parts that is every tire pressure monitoring system and main board or display screen indicates status of all tires pressure and interconnected through wireless technology. In each tire pressure monitoring set there is a small kit consists of micro-controller, sound alarm, pressure sensor and battery. This small kit senses high and low air pressure inside the tire and informs to main circuit mounted on the display screen. Because of which driver or rider will come to know the air pressure status of every tire and can take appropriate action. Here sound alarm introduced in small kit to identify high pressure level if air inside the tire exceeds the de�ned level then sound alarm is generated. Light blinking facility is provided on the display screen to show low air pressure status of any tire. This communication between main circuit (display screen) and every tire kits is done through wireless medium which can be Wi-Fi or Bluetooth. The wireless charging is done to charge small tire kit though vehicle has main battery backup or charging point inside the vehicle. To protect the tire pressure kit from problem of overheating, cooling substance or cooling liquid is used as heat an absorbent around the kit, which helps to maintain kits long life. Due to use of such technology road accidents caused due to low air pressure of tires can be avoided. The proposed technology gives information of all tire pressure to the user on the display screen, which minimizes human efforts to check air externally. Also cost on the air check instruments can be minimized due to this proposed work.
