Description

The manufacturer states that the sensor operates in the range from 4 cm to 700 cm. Our tests show that it behaves correctly in the range from 4 cm to 400 cm. The module is powered by 5 V, the output is a signal whose duration is proportional to the measured distance. To operate the module there is a library for Arduino users .

Arduino compatible product

The library and wiring diagram of Arduino can be found at this address.

Use

To start the measurement, a voltage pulse (high state 5 V) must be applied to the TRIG pin for 10 uS. The module measures the distance with a 40 kHz sound wave.Asignal is sent to the microcontrollerwherethedistance depends on the duration of the high state and can be calculated from the formula:

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

where:

  • distance test - distance measured
  • high level time - duration of high state
  • velocity of sound - speed of sound wave propagation in air - 340 m/s

To get the result in mm you can use the formula:

distance [mm] = ( high level time × 34 / 100 ) / 2

The measurement procedure is shown in the figure below.
