HC SR-04 Mesafe Sensörü #TK #5

HC SR-04 Ultrasonik ses dalgaları ile çalışan bir mesafe sensörüdür. Üzerinde ultrasonik ses alıcı/verici çifti vardır. Bu sensörler yine aynı kart üzerindeki entegreler ile işlenerek mesafe ölçümü yapılır. Yapılan ölçüm özel bir protokolle mikrodenetleyiciler tarafından anlaşılacak şekle getirilir.

Ultrasonik sensörler üzerindeki verici modülden bir ses dalgası gönderir ve diğer modülden bu ses dalgasını okur. Sesin hızı neredeyse sabit olduğu için sesin gidip gelme süresinden mesafe ölçülür.

İşin temelinde fizikte öğrenilen x=vt formili vardır.

x: yol
v: hız
t: zaman

hız sabit, zaman ölçülüyor ve buradan yol/mesafe hesaplanabiliyor.

HC SR-04 e ait datasheet bilgileri aşağıdaki gibidir.

HC SR-04 4 pine sahiptir. Bunlar;

  • VCC
  • Trig
  • Echo
  • GND

VCC, GND +5V besleme girişidir.

Ölçüm başlatmak için Trig pinine >=10uS lik bir pulse uygulanır. Sonrasında ölçüm başlar. Sonrasında Echo pininin high kalma süresi mesafeyi ifade eder.

Mesafe ölçüm formülü;

Test distance = (high level time×velocity of sound (340M/S) / 2

HC SR-04 okumak için kullanılabilecek arduino kodu aşağıdaki gibidir;
