Story

Do you have trouble sleeping because you're worried someone may break into your home? Not anymore with our small but mighty security system. This system will fit in many discreet locations to track any motion by your front door. Once motion is detected, a buzzer will activate and a notification will be sent to a device of your choosing! So no matter where you are, you will be alerted when any motion is detected. This device is lightweight, easily transported, and incredibly cost-effective. Our group decided on this device because it is something everyone could use and love. This device works with the help of one code that activates both particle photons.

Utilizing two particle photons, our security system operates by the "Primary" photon, which collects data from the motion sensor, talking to the "Secondary" photon which activates the buzzer once the motion sensor data has been received. The motion sensor photon also sends notifications via the Pushover app to alert the user when motion is detected. This is very useful, as alerts can be received no matter how far you are from home.

This security system was simple to make, with inexpensive components, which could be installed anywhere. This device is useful for all types of customers.

Code

int buzzerPin = D0;                 
int inputPin = D1;               
bool available = false;          
int motionCounter = 0;           
bool loadfirst = false;

Timer timer(30000, determineMotion);

void setup() {
  pinMode(buzzerPin, OUTPUT);   
  pinMode(inputPin, INPUT);      
  determineMotion();
  timer.start(); 
}

void determineMotion() {    
    if(motionCounter < 1) { 
        if(loadfirst == false){
             loadfirst = true;
             motionCounter = 0;
             Particle.publish("apartment", "Motion Detector Starting", PRIVATE);
             delay(500); 
        }

    digitalWrite(buzzerPin, LOW);
