HC-SR04

Quick Decision Notes

HC-SR04 is indexed as a sensors part from Generic. ChipScout tracks it by practical maker-facing dimensions: interfaces, library readiness, estimated price, field-level sources, and whether the page is strong enough for selection rather than only lookup.

Pinout Table

Pinout is not yet source-verified. Use the table as an integration checklist, then confirm exact pins against the module vendor page before wiring hardware.

Common Wiring

Arduino Example

void setup() {
  Serial.begin(115200);
  Serial.println("HC-SR04 GPIO wiring smoke test");
}

void loop() {
  // Replace with the maintained HC-SR04 library or module protocol.
  Serial.println("Read or toggle the connected signal pin.");
  delay(1000);
}

MicroPython Example

from machine import Pin
import time

signal = Pin(0, Pin.IN)

while True:
    # Replace with the maintained HC-SR04 driver or module protocol.
    print("HC-SR04 signal:", signal.value())
    time.sleep(1)
