Description

Waterproof ultrasonic sensor operating in the range from 20 cm to 450 cm. It is powered with voltage of 5 V. The output is a signal whose duration is proportional to the measured distance. The sensor is compatible with popular sensor HC-SR04, which means that the sample programs and libraries will work correctly for both sensors.

We encourage youto see the user's guide which includes a sample programfor handling ultrasonic sensors with Arduino.

The sensor has four leads that are compatible with themodule HC-SR04:VCC- supply voltage 5 V,GND- mass of system and the signal pins - EchoandTrig.

Method of application

To begin the measurement, you must indicate on the TRIG pin, pulse voltage (high state of 5 V) for 10 us. The module measures distances using sound wave with a frequency of 40 kHz. To 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 projecting the sound waves in air - 340 m/s

 

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

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