i am using arduino uno and trying to coonecting with this sensor , but it gives false reading , i have directly connected it with vcc to 5v , gnd to gnd and trig, echo to digital pins on arduino ., on the datasheet i saw it is compatible with arduino Leonardo , so isnt it be working with arduino uno ? , the code is : const int trigPin = 9;
const int echoPin = 10;

const int sampleSize = 5;
int readings[sampleSize];
int index = 0;
long total = 0;
int average = 0;

void setup() {
 Serial.begin(9600);
 pinMode(trigPin, OUTPUT); 
 pinMode(echoPin, INPUT); 
 for (int i = 0; i < sampleSize; i++) {
   readings[i] = 0;
 }
}

void loop() {
 // Measure the distance
 digitalWrite(trigPin, LOW);
 delayMicroseconds(2);
 digitalWrite(trigPin, HIGH);
 delayMicroseconds(10);
 digitalWrite(trigPin, LOW);
 
 long duration = pulseIn(echoPin, HIGH);
 int distance = duration * 0.0344 / 2;

 // Apply the moving average filter
 total = total - readings[index];
 readings[index] = distance;
 total = total + readings[index];
 index = (index + 1) % sampleSize;
 
 average = total / sampleSize;
 
 Serial.print("Measured Distance: ");
 Serial.print(distance);
 Serial.print(" cm. Average Distance: ");
 Serial.println(average);
 
 delay(1000);
}
