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

Question: The sensor reads 2 - 400cm, not up to 200cm. That's what the documentation says.
Answer: The sensor can measure longer distances, but the best accuracy is for ranges up to 200 cm.

The product meets my expectations, it's okay
BARTOSZ 15.01.2024 Confirmed purchase Translated review
I rated this item as an excellent addition to my Raspberry Pi-based project. The quality is impressive, the ease of installation and compatibility with Raspberry Pi make using the product a pleasure.
Adam 23.07.2023 Confirmed purchase Translated review
it's ok. This module is about 30 times cheaper than at TME
Bartosz 12.06.2023 Confirmed purchase Translated review
Revelation
Sławomir 07.03.2023 Confirmed purchase Translated review
I recommend :)
Mirosław 27.12.2022 Confirmed purchase Translated review
I use it and it's ok, mmo knows how to derive the original signal from the receiver
Przemysław 01.10.2022 Confirmed purchase Translated review
Sometimes there are measurement errors, but in the described range it works surprisingly well for equipment at such a low price. It is enough for simple projects requiring object detection or medium-precision measurements.
