Abstract
A multifunctional tire pressure gauge for a car functions to measure the inner temperature of the car, the voltage of the car battery and the tire pressure of the tire. Thus, when the plug is inserted into the cigarette lighter of the car, the tire pressure gauge can be used to measure the temperature of the inside of the car and the voltage of the car battery simultaneously. In addition, after the plug is removed from the cigarette lighter, the tire pressure gauge functions as a portable tire pressure gauge.
