= HCSR04 ultrasonic sensor Library for Arduino =

HCSR04 is an Arduino library HCSR04 Sensors

HC-SR04

Documentation

Documentation for the library is on the Github Project Pages

basic example

schéma HC_SR04_cabling

#include <HCSR04.h> HCSR04 hc(2, 3); //initialisation class HCSR04 (trig pin , echo pin) void setup() { Serial.begin(9600); } void loop() { Serial.println( hc.dist() ); //return current distance (cm) in serial delay(60); // we suggest to use over 60ms measurement cycle, in order to prevent trigger signal to the echo signal. }

if you want use a multiple sensor schéma HC_SR04_multi_cabling

#include <HCSR04.h> HCSR04 hc(2, new int[6]{5, 6, 7, 8, 9, 10}, 6); //initialisation class HCSR04 (trig pin , echo pin, number of sensor) void setup() { Serial.begin(9600); } void loop() { for (int i = 0; i < 6; i++ ) Serial.println( hc.dist(i) ); //return curent distance (cm) in serial for sensor 1 to 6 delay(60); // we suggest to use over 60ms measurement cycle, in order to prevent trigger signal to the echo signal. }
