Story

We have designed and implemented a motion sensor light that could have many uses. The design was originally intended for places like a basement or garage where foot traffic is is more rare, to help save power by only being on when motion is detected. While it could be used like this, it could also be implemented into other rooms as well to save energy more often. The design is minimally invasive and could be set up in any room or space with ease. With our knowledge of coding and sensors, we were able to set this project up with few hiccups, and make a functioning motion light.

Code

int inputPin = D4;              
int ledPin = D7;                
int pirState = LOW;             
int val = 0;
int ledout = D6;
int calibrateTime = 10000;      

void setup()
    {
        pinMode( ledPin, OUTPUT );
        pinMode(inputPin, INPUT);   
        pinMode(ledout, OUTPUT);
        digitalWrite(ledout, LOW);
        Particle.subscribe("Noahs_Argon", myHandler);
    }

void loop()
    {
        if ( calibrated() )
            {
               readTheSensor();
               reportTheData();
            }
    }

void readTheSensor() 
    {
        val = digitalRead(inputPin);
    }

bool calibrated() 
    {
        return millis() - calibrateTime > 0;
    }

void reportTheData() 
    {
        if (val == HIGH) 
            {
                Particle.publish("3171", "1"); 
                pirState = HIGH;
                setLED( pirState );
                delay(60000);
            } 
            
        else 
            {   Particle.publish("3171","0");
                pirState = LOW;
                setLED( pirState );
                delay(30000);
            }
    }

void setLED( int state )
    {
        digitalWrite( ledPin, state );
    }

void myHandler(const char *event, const char *data)
    {
        digitalWrite(ledout, HIGH);
        delay(5000);
        digitalWrite(ledout, LOW);
    }
