So instead of a resistor, you'll need a transistor circuit to produce the higher voltage under the gpio's control.
Ultrasonic sensors can detect objects up to ten meters away and take numerous range measurements per second.
This circuit does not have the ability to estimate distance; it merely emits a sound when an object passes in front of it. Because it is an analog method, no microprocessor or Arduino is required. It has a detecting range of around 12 inches. For a better experience, you must alter the preset.
The ECHO(PWM) sensor emits a brief 40 kHz (ultrasonic) wave under the control of a host microcontroller (trigger pulse). This burst passes through the air, collides with an item, and returns to the sensor.
