  • Test Distance Formula -- The distance between the unit and the object is calculated by measuring the traveling time of sound and output it as the width of a TTL pulse,hc-sr04 test distance following formula -- L = 1/2 ร— T ร— C ( L is the distance, T is the time between the emission and reception, and C is the sonic speed )
  • Package include -- 5 X HC-SR04 ultrasonic sensors blocks module, 10 X female-male cables , 10 X female-female cables , 3 X HC-SR04 mounting bracket
