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.
