PUMP IT SYSTEMS

To deliver an e�cient, user-friendly automated air pump system that ensures accuracy and promotes proper tire in�ation.

INPUT METHODSInput Method 1: The user is able to manually enter the desired PSI value using the input buttons.

Input Method 2: The system can take an input from an RFID tag attached to the object, allowing any user to easily enter the correct PSI value.

SYSTEM DIAGRAM SOLUTION

PROJECT DESCRIPTIONThe Automated In�ation System eliminates the need to frequently check pressure values while in�ating objects. Using a pressure sensor, a microcontroller controls two valves to in�ate and de�ate objects to desired values.

FACTS

The average Canadian driver could save the equivalent of two weeks worth of gas every year with proper tire in�ation.

Every year in Canada, 1.5 million tonnes of carbon dioxide are unnecessarily released into the environment because of poor tire in�ation.

Underin�ation will build up internal heat, increase rolling resistance and cause a reduction in fuel economy. You would experience a signi�cant loss of steering precision and cornering stability.

Under or over-in�ated tires will cause handling, Antilock Braking Systems, Traction Control Systems, and stability control systems problems.
