Story

Introduction

Every college student fears a home invasion, especially when living alone without a home security system. Before they sleep, they check whether the window is closed several times and barricade the door with several chairs and dressers. Well, with this ingenious invention called "The College Friendly Security System", college students can now sleep at peace.

College Student's Door at Night

This innovative security system is equipped with a buzzer that will sound once the a window or door has been opened. In addition to the buzzer, this alarm is also equipped with an email notification that will be sent to the student once someone enters their apartment.

Additionally, this handy security alarm can also be used to detect whether the window has remained open for a long interval of time. For example, if a college student leaves their apartment or dorm, this system is capable of notifying them that the window has remained open and that they should return home and close it.

Procedures

For the execution of this project, three Photons, two proximity sensors (reed switches), duct tape, power cable, and a power source were used. The first photon was used for the door sensor, the second for the window sensor, and the last photon was used for the buzzer. The door sensor shown in the figure below was connected to both sides of the door using duct tape, and its signal (output) was transmitted to the buzzer Photon.

Door Sensor

The window sensor shown below was also connected on both sides of the window using duct tape, and its signal (output) was also sent to the buzzer photon. Once the buzzer photon received signals that the door or window were open, an alarm went off and an email, using If This Then That, was sent to the student notifying them the door or window has been opened.

Window Sensor

The buzzer was located in the student's bedroom and was able to be heard throughout the apartment. This buzzer with its associated photon, was in charge of initiating the publish and subscribe event

One of the many advantages of this innovative security system is that the buzzer will not cease until the door or window has been closed. Thus, informing the student every two minutes of window or door activity. Also, this security system is able to be placed on any window or door and is capable of transmitting a wide variety of outputs.

Displayed below is a video explaining the usage and experimentation of this college friendly security system.

Experiment Demonstration

With this security system in place, there is no need for barricades or long sleepless nights. College students can now sleep in serenity knowing that they are safe from unwanted predators.

Code

 int inswitch = D1;               // choose the input pin (for reed swtich)
 int pirState = 0;             // we start with the door/window closed
 int val = 0;                    // variable for reading the pin status
  
void setup() {
  
  pinMode(inswitch, INPUT);     // declare switch as input
Particle.variable("pirState", &pirState, INT);
    Particle.variable("val", &val, INT);

     delay(12000);
