Ultrasonic Distance Sensor (4-pin)
Layout symbol
Distance sensor (like the HC-SR04) that sends out an ultrasonic ping and listens for the echo. Send a 10 µs pulse to TRIG; ECHO then goes high for as long as the sound took to travel there and back, about 58 µs per cm of distance. Runs on 5 V, and its ECHO output is 5 V, so use a voltage divider on 3.3 V boards.
