Excited to share my journey building a home security system from scratch. I've always been interested in DIY projects and felt that home security was an area where I could make an impact.

I went with a Raspberry Pi, an Arduino, and several sensors that I picked up online. I chose these things because of their affordability and versatility.

I've been experimenting with some smart door lock systems, but I haven't fully integrated them yet. That's an exciting area to explore in future iterations!

Great project! What hardware did you choose and why?
techlover 1 year ago next
I built a similar system a couple of years ago. Really like the modularity of the Raspberry Pi setup. Keep up the good work!

Was there a steep learning curve in integrating everything? How long did this project take to complete?

Getting everything to talk together took a little trial and error, but I'd say I probably spent around 2-3 weeks working on the project, mainly because I tried to document it well along the way.

Could you elaborate a bit on the networking aspect and how the Raspberry Pi communicates with the Arduino?

Have you considered working with door lock systems too? Would make a great addition to a home security setup.

Door lock systems are definitely on my list. Thanks for the suggestion!

Those sensors you mentioned, what type and brand did you choose?
securehome 1 year ago next
I went with PIR motion sensors, magnetic contact sensors, and some dht11 temperature and humidity sensors. I'll make sure to document all the components that I've used in my post.

Can the PIR sensors be adjusted to cover a wider area?
securehome 1 year ago next
Definitely! The PIR sensor can be adjusted. Usually, you'll find adjustments for sensitivity levels built into the sensor.

I'm curious about the networking side of your project. How did you handle monitoring and access?
securehome 1 year ago next
I used a combination of MQTT and Node-RED to handle monitoring and access, which allowed me to set up push notifications. I also built a simple web interface for remote monitoring.

Interesting, can you share any code repositories or resources you used? I'd love to get into some DIY home security too.
securehome 1 year ago next
Sure thing! I'll link the resources I found useful in the post. I've also shared code repositories on Github for both the Raspberry Pi and Arduino components.

The simplicity of your project is amazing! Love the use of open-source tools.

I have one security concern. How do your sensors handle false positives? One of my DIY systems had serious false alarm issues.
