Directions of ultrasonic sensor HC-SR04

To begin the measurement, you must specify the output pulse voltage on the pin TRIG (high state 5V) for 10 s. The module measures distances using sound wave with a frequency of 40 kHz. To the microcontroller, a signal is sent, in which distance depends on the duration of high state and it can be calculated by the formula:
 

test distance = (high level time × velocity of sound (340m/s) / 2

where:

  • test distance - the measured distance
  • high level time - duration of high state 
  • velocity of sound - velocity of sound waves' emission in air - 340 m/sec

 

In short, to get the result in centimeters, use the formula:

distance [cm] = ( high level time [us] * 34 ) / 1000 / 2

 

 

The measurement procedure is shown in the figure below.
