WTPMS: Wireless Tyre Pressure Monitoring System for Motor Vehicles

Wireless Tyre Pressure Monitoring System for Motor Vehicles (WTPMS) is a tyre pressure monitoring system used in any type of the vehicles. This technology involves two parts that is all tyres pressure monitoring system in motor vehicle and main board or display screen indicating status of all tyres pressure and intercommunication through wireless technology. In each tyre 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 tyre 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 tyre and can take appropriate action. The sound alarm introduced in small kit is to identify high pressure level; if air inside the tyre exceeds the defined level then sound alarm is generated. Light blinking facility is provided on the display screen to show low air pressure status of any tyre. This communication between main circuit (display screen) and every tyre kits is done through wireless medium which can be Wi-Fi or Bluetooth. The wireless charging is done to charge small tyre kit though vehicle has main battery backup or charging point inside the vehicle. To protect the tyre pressure kit from problem of overheating, cooling substance or cooling liquid is used as heat absorbent around the kit, which helps to maintain kit's long life. Due to use of such technology road accidents caused due to low or too much high air pressure of tyres can be avoided. The proposed technology gives information of all tyres' 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.
