Technical Examples
- The tire pressure gauge has a body, a controller and a cap. The body has a valve stem connector that attaches to a valve stem of a tire to sample internal air pressure of the tire. The controller is mounted inside the body and includes a microprocessor, a pressure sensor, an alarm unit and a pressure indicator. The microprocessor stores a preset pressure value. The pressure sensor senses the tire's internal air pressure sampled by the valve stem connector, generates an electronic signal indicating the sensed pressure and sends the electronic signal to the microprocessor. The microprocessor compares the electronic signal to the preset pressure value. If the electronic signal is lower than the preset pressure value, the microprocessor activates the alarm unit that produces an audible warning.
