In this project we will be using the 4G LTE Network and a Radar Human Presence sensor to create a new and modern alarm system. Due to the 4G Network and LTE-M you can send alarm notifications super fast to your phone, while it costs you pretty much nothing. Combine that with a precise radar and loud siren and you got yourself an awesome alarm system that will protect your treasures ;-) Let's get started!

You should always use black boxes, or maybe colored pixel noise instead.

@iGThomas Рік тому
As somebody who work myself for an international IoT/M2M telecom operator, we have a lot of customers having this kind of setup (although still with 2G.... so props for using LTE-M). I'd recommend to make some check on the device so that it's always connected to the cloud or that it can atleast ping it. Due to technical maintenance on the cells we send a "CancelLocation" event to disconnect the SIM and perform works and some devices think they still have a PDP session ongoing and keep trying to send MQTT payload and are stuck behind this loop where the operator already closed the PDP session but the device still sees it being open and uploads data without checking if it's acknowledged. Make sure to once in a while send some TCP type of packets and if they don't succeed then fully reboot the device or send the AT command AT+CFUN to reboot the whole module. It's best to fully reboot reboot the module rather than check if the PDP session is still open and try to reopen it. Also You might try to check the NB-IOT technology it's even more light weight incase you want to use it in an area where there's no electricity and you send data only when the module wakes up (coverage is even better than LTE-M) These are my two cents good luck and great video! :)

My only concern is it looks like you installed it right next to the door with the buttons facing anyone entering. A thief could just hit the off button quick before any detection.

@michaegi4717 Рік тому
Awesome project!!! I want to give few hints regarding radar sensors: 1. you can buy those sensor based on different frequencies. Ensure that the choosen frequency is allowed in you region for your application. Having a wrong radar running might disturb other electronics near by... and at least in Germany you can get serious trouble if someone calls the autorities because you block a certain frequency band. 2. Be aware that radar might be disturbed by any metal. Facing this e.g. to the garage gate might cause some problems. 3. Be aware that the sensor might look through walls 🙂

the fact that you can power everything with 12v means you can get one of those 12v ups power supplys (commonly sold in LED shops). it is a regular 12v supply with additional leads for lead-acid battery. by this you can avoid being vulnerable to the theif taking down your power breaker because the system will resume from the lead-acid battery. you can use regular motorbike batteries that are smaller in size (about 7-9Ah)
@badarjahangirkayani6196 Рік тому
Nordic products are very capable but programming them can be challenging, especially if you do it using nRF Connect SDK which is built on top of Zephyr. Once an arduino port for this board comes out, like it has for other nordic boards, life will get a lot easier and you will see these being used a lot more in hobby projects and products alike.
@LeeeHack Рік тому
I can agree that Zephyr (and therefore also NCS) can feel a little overwhelming at first, but from my own experience I can say, that once you get past the setup and get an understanding of how the DeviceTree and Driver configs/overlays work, the rest really becomes pretty simple and really efficient to work with (especially with the ton of samples they provide).

@mondotv4216 Рік тому
Sorry - he's got an alarm with a cellular connection. The whole idea of an on/off switch is ridiculous. The alarm should always be powered but armed and disarmed from the phone via a code. Yep, more complicated but what modern alarm doesn't have code based security. I don't want to get too much into feature creep but that is a very low cost add on (a 4G receiver/transmitter rather than just a transmitter). And a small lithium ion battery backup. Easy and right down Great Scott's alley. I see an alarm 2 point zero coming.
@spocksvulcanbrain Рік тому
Great project and nicely done. I would have made one different decision. I can't tell from your video if you turned down the volume when the alarm was on, but it doesn't sound very loud or piercing. If not, I would have scrapped an old smoke alarm for its siren - they are loud, annoying, and would definitely cause intruders to not stick around. Additionally, that flashing alarm is awfully expensive if some of us out here wanted to recreate your project.
@jayduffy7615 Рік тому
You should mount the alarm box in a safe all by itself. Run the wiring for the accessories (sensors, speakers, lights, cameras, microphones, etc.) Out of the bottom or out of the back of the safe. Secure the safe to the floor or the wall, if you can. A burglar could waste so much time on trying to take or to breach that safe. As they waste their time, notifications are being sent, photos, audio recordings, or video could be taken, and sent. Alarms could be making loud noises while strobe lights flash and disorent the intruder. So even if they smashed the speaker or the lights, they still wouldn't be able to stop the notifications or the audio/video recordings from being sent. Another option would be to mount the alarm box in some other location, still use a dummy safe that is either too heavy to move or bolted to the floor or wall, and mount all of the alarm accessories in the areas needed to protect your valuables.

random thought if you could add manual triggers run a wire to say your bike and use magnets around it as a switch so if the wire is removed without entering a code into the console the alarm activates this idea can be improved on but be a nice manual trigger for more expensive stuff could be used on the door also to just send an alert with option to call police when the door is opened

Hey Scott, what type of filament did you use to print the housing of the electronics?
@BryceDixonDev Рік тому
8:30 small nitpick, but that's Visual Studio Code. Visual Studio (IDE) is actually (confusingly) different software built on an entirely different codebase.

Hmm. A potential cool upgrade would be to add a way to arm/disarm the alarm through a phone and maybe remove the physical arm/disarm options in case the potential thief sees them and can turn it off.

I may have missed it - is there a method to disarm the system before entering the protected area? Nice work. Thanks.

Great project, you might have thrown a battery backup in there though incase of a power outage.

Very Nice! I need to build a theft device for my ebike. So if somebody starts riding it, it sends an alert, and also gives an accurate GPS location that can't be turned off.. So built into my battery side by side with the BMS. I have that BMS that everybody uses in their DIY solar projects, so I do know it has a GPS add on that plugs right into it that China sells for around $40 usd.. But where's the fun in that? It would also be cool if I could stream voice through it to a small bluetooth speaker under the seat so I can just tell the thief I know where he's at and it would be best for him to just walk away from the bike.

Thanks :-) I hope so.

Notice that the mosquitto test instance is not guaranteed to be available in any way - it's a test instance only. Also, Android phones love to shutdown or delay background services for battery saving. I wouldn't want to rely on an alarm set up like this. (Sorry for the negativity, but I've been working in IoT long enough)

A keypad for PIN disarming might be a bit more secure...

This is absolutely amazing. Scott, you always make the best content and everyone can try their own projects at anytime!. Defiantly deserve more recognition for your hard work, Why does Mr Beast get a follow base 😆 People need too learn stuff that is useful on the internet! We need innovation.

Interesting project, why not add some bright flashes to blind the thieves, have the switch in a different room to not get flashbanged yourself when approaching it.

Very interesting project, I find that DevAcademy is really usefull to get up to speed on the more professional development environment offered by Nordic. 🤔 Lots of fun for the more cerebral amongst us I would say!

So you connect that huge nRF9160 (175 €) board to an arduino just to send out data via LTE-M - a job that tiny boards (for arduino) less than half the price can do?
GreatScott!
