MAKER FACTORY 2134052 Ultrasonic Sensor Module Instructions

MAKER FACTORY 2134052 Ultrasonic Sensor Module

Description

The module is an ultrasonic sensor that senses oncoming objects and their distance to the sensor.

Pinout / Pin Map

Example Application

In this example we will make the sensor detect an oncoming object and report the measured distance.

The instructions use the Arduino® platform to illustrate product use. You can also use an Arduino derivative or another platform that supports this type of product.

Connection

Make sure you switch resistors between LED/Module and developer board as listed in the connection table or shown in the connection diagram to prevent damaging your com-ponents.

Code

• define trigPin 12
• define echoPin 13
• define led 11
• define led2 10

void setup

• Serial.begin (9600);
• pinMode(trigPin, OUTPUT)
• pinMode(echoPin, INPUT)
• pinMode(led, OUTPUT)
• pinMode(led2, OUTPUT)

void loop

• long duration, distance;
• digitalWrite(trigPin, LOW);
• delayMicroseconds(2);
• digitalWrite(trigPin, HIGH);
• delayMicroseconds(10);
• digitalWrite(trigPin, LOW);
• duration = pulseIn(echoPin, HIGH);
• distance = (duration/2) / 29.1;
  // This is where the LED On/Off happens

if (distance < 4) { // When the Red condition is met, the Green LED should turn off

• digitalWrite(led,HIGH);
• digitalWrite(led2,LOW);
• digitalWrite(led,LOW);
• digitalWrite(led2,HIGH);

if (distance >= 200 || distance <= 0){ Serial.println(“Out of range”); else

• Serial.print(distance);
• Serial.println(” cm”);
• delay(500);

Procedure

1. Prepare a sketch with the given code and upload it to your board.
2. Connect the module/component to the board as shown in the connection diagram or table.
3. Approach the sensor within its range with an object.
4. Measurements are output to the Serial Monitor.
