In this project we created a home alarm system using the particle photon. Through this, we can connect to the internet and send messages directly to our phone whenever someone enters our house.

Home Alarm System Video

This video demonstrates the Particle Photon: Home Alarm System and how it works.

Project Pitch:

College apartments and dorms can have a high traffic volume which can be quite unnerving to some. Our group has decided to create a door alarm system that can ease this dilemma and keep the user up to date with anything going on around their home. This alarm system will rely on an ultrasonic sonar proximity sensor (HC-SR04), a buzzer, two LED diodes, and a particle photon for internet connectivity. This device will work by attaching the proximity sensor system next to the doorway that the user wants to keep track of. The proximity sensor will be aimed at a tab that is on the door, which is where a consistent distance reading will come from. The systems sensor will repeatedly take distance measurements every few milliseconds. Once the door is opened and the tab is out of the way, the sensor will read a distance greater than the set threshold distance. This will trigger the alarm system and will alert the user through a message to their phone (through the particle photon and IFTTT internet services). For users that are present, they will be alerted by a buzzer that sounds every one second, along with a red LED light that will turn on with the buzzer. This device will be able to be turned on and off from a HTML website. When turned on by the HTML website, the system functions like it normally does and when it is turned off none of the components function and the system is inactive. The system also has a green LED light that will be turned on when the device is functioning and turned off when the system is not functioning. Through these features, we have a functioning alarm system that will give its users a sense of ease by allowing them to know whenever someone has entered/left their home.
