This simple alarm is inexpensive, reliable, and easy to use. It is ideal for apartments or other places where a full security system cannot be installed. It is removable so it will not cause any permanent damage to walls and perfectly fits across a single entrance way; multiple motion sensors could be added to other entrances if wanted.
How it Works
1 / 3 • Alarm and sensor setup
The alarm operates using a PIR motion sensor on one breadboard with a particle photon that sends an alert to the cloud when motion is detected. The cloud sends a signal to the other photon which then sets off the alarm. Motion alerts are shown on the Particle console and using IFTTT are also sent to Google Sheets. The user can monitor the signals when they are sent to see if any unexpected guests have been in their home.
