Home Security
A smart home is a safe home. In this guide, we're going to take our cardboard smart-home and equip it with sensors to protect the home against intruders, wanna-be burglars, and invisible chemicals.
What is the IO Home?
Interested in making your house a bit smarter? Why not start small by building a Cardboard Smart Home! Adafruit IO Home is a series of learning guides covering all aspects of a smart house: from temperature monitoring to an intelligent home security system.
Want to scale up from the cardboard home to a real home? We've selected real-world components, sensors, and hardware which can also be installed in your home, office or laboratory!
Door Sensor
We'll be building a small front door (out of cardboard, of course) for our home. We'll use a reed switch and magnet to detect if the door is open or closed. We'll be adding a toggle-block on our Adafruit IO dashboard to arm/dis-arm the system.
Motion Sensor
We'll also utilize a PIR sensor to detect any intruders who hang out in front of our house after dark.
Air Quality Sensor
Now, what about the thing most people don't think to monitor? We're talking about invisible intruders - gasses and air particulates. While gasses and volatile organic compounds are already inside your home - you'd benefit from adding the ability to measure them. The SGP30 Air Quality Sensor is one of our favorite sensors - it can monitor both the amount of Carbon Dioxide and Volatile Organic Compounds in your home's air.
Alarm System
A piezo buzzer and a NeoPixel Jewel are used in this guide as a combination of visual and audio alerts to notify you when your home has detected an after-dark intruder.
To use this guide, we'll need a microcontroller capable of connecting to Adafruit IO. The Feather HUZZAH with ESP8266 is used in most of our Adafruit IO Guides.
Tools
Owning, or having access to, these tools will make this guide much easier to follow. If you do not have access to them, pick some up from the Adafruit Store.
- X-Acto Knife, Box Cutter, or Sharp Knife
- Hot Glue Gun
- Double Sided Tape
