Detailed Description

• ID: groveultrasonic
• Name: Grove Ultrasonic Ranger
• Category: sound
• Manufacturer: seeed
• Connection: gpio

This Grove Ultrasonic sensor is a non-contact distance measurement module which is compatible with the Grove system. It is designed for easy modular project usage with industrial performance. Detection ranges from 3 cm (1.2") to 4 m (13'1.5") and works best when the object is within a 30 degree angle relative to the sensor.

  // upm::GroveUltraSonic *sonar = NULL;
  sonar = new upm::GroveUltraSonic(2);
  while(running) {
    int width = sonar->getDistance();
    printf("Echo width = %d\n", width);
    printf("Distance inches = %f.2\n\n", width/148.0);
    sleep(3);
  }

Constructor & Destructor Documentation

GroveUltraSonic

(

uint8_t

pin

)

Instantiates a GroveUltraSonic object

Parameters

pin	pin for triggering the sensor for distance and for receiving pulse response

~GroveUltraSonic

(

Member Function Documentation

int getDistance

(

)

Returns the echo's pulse width from the sensor in microseconds. Divide by 58 to convert distance to centimetres. Divide by 148 to convert distance to inches.

std::string name ( )

inline

Return name of the component

bool working ( )

inline

Returns true while the sensor is busy waiting for the echo pulse
