Motion Sensor Phidget

The Motion Sensor Phidget allows you to detect motion up to ten meters away (approximately 30 feet).

​ This Phidget returns a constant voltage when no objects are detected. When motion is detected, the voltage will increase or decrease.

See tutorial

Setup

Before you do any coding you will have to attach your Motion Sensor Phidget to your VINT hub as shown:

Code (Java)

Create a file called Motion and add the following code. Run your code. Move your hand over the motion sensor to see the value change.

package motion;

//Add Phidgets Library
import com.phidget22.*;

public class Motion {
    public static void main(String[] args) throws Exception{
        //Create
        VoltageInput motionSensor = new VoltageInput();
        
        //Address
        motionSensor.setHubPort(0);
        motionSensor.setIsHubPortDevice(true);

        //Open
        motionSensor.open(1000);
        
        //Use your Phidget
        while (true) {
            System.out.println("Motion Value: " + motionSensor.getVoltage());
            Thread.sleep(250);
        }
    }
}
  
  
//Add Phidgets Library
import com.phidget22.*;

public class Motion {
    public static void main(String[] args) throws Exception{
        //Create
        VoltageInput motionSensor = new VoltageInput();
        
        //Address
        motionSensor.setHubPort(0);
        motionSensor.setIsHubPortDevice(true);

        //Open
        motionSensor.open(1000);
        
        //Use your Phidget
        while (true) {
            System.out.println("Motion Value: " + motionSensor.getVoltage());
            Thread.sleep(250);
        }
    }
}
  
  
//Add Phidgets Library
import com.phidget22.*;

//Define
VoltageInput motionSensor;

void setup(){
  try{
    
    //Create
    motionSensor = new VoltageInput();
    
    //Address
    motionSensor.setHubPort(0);
    motionSensor.setIsHubPortDevice(true);
    
    //Open
    motionSensor.open(1000);
    
  }catch(Exception e){
    e.printStackTrace();
  }
}

void draw(){
  try{
    
    //Use your Phidgets
    println("Motion Value: " + motionSensor.getVoltage() + " V");
    delay(250);
    
  }catch(Exception e){
    e.printStackTrace();
  }
}

Applications

The Motion Sensing Phidget uses infrared light to detect motion. Motion sensors commonly used as an integrated component of security systems and lighting control systems.

Practice

Use the Motion Sensing Phidget to create a mock security system. If an object is detected, blink the red LED. If there is no movement, the green LED should stay on.

Check out the advanced lesson Using the Sensor API before you use the API for the first time.

API

This device doesn't have an API of its own. It is controlled by opening a VoltageInput on a VINT Hub.

Troubleshoot
  1. Make sure everything is plugged in properly and your VINT Hub is connected to your computer
  2. Stop running other programs that are using your Phidgets before running a program.

If these do not solve your issue visit the Advanced Troubleshooting Page.

What are Phidgets?

Phidgets are programmable, modular USB devices, either sensors or controllers that you can connect together. Simply write code in your favorite language and solve real-world problems.
