Ultrasonic Distance Sensor (3-pin)

Schematic symbol

Ultrasonic distance sensor with a single signal pin used for both trigger and echo. The microcontroller sends a short pulse, then switches the pin to input and measures how long it stays high. That time is the sound's round trip, about 58 µs per cm of distance.
