Hi guys, after years i went back to arduino. I have one project in my mind and I want to discuss with you if it is feasible or it still needs to tune up.
I go camping quite often and few times happened to me that some people was sneaking around my place. I was scared somebody trying steal my things. This is a reason why I got idea make some kind of alarm with few motion sensors placed around a place and with receiver in tent. If some sensor catching a movement then send signal to transmitter activate buzzer (probably piezoelectric) and some LEDs.
On the beginning I would start with 4 transmitters with PIR sensor and one receiver.
Which way do you recommend to go?
use 5 arduino nano boards (4 for transmitter + 1 for receiver)
use 1 arduino nano board (only for receiver)
I choose arduino nano because I have more experiences with this board, but my question is if arduino nano is not so big for this project and if exist smaller board to be used for this small project.
I would use 433mhz module (transmitter+receiver) because distance around receiver will not be longer than 10m.
If you have some other ideas or any comments do not hesitate comment below or make fun of me
Hiking and camping are loads of fun, but is tech the solution? Maybe ANIMALS sneak around and take anything not hanging high, out of reach in a far-away tree (bear-hangs), and why hike with valuables? Leave the kilograms at home. Hike light. Enjoy nature.
Paul, paul, paul... paul, paul, ... paul, paul. Tin cans went out with canvas tents. : )
Some eBay sellers will sell the transmitters and receivers separately so you don't have to buy them in pairs
You could use attiny85 for the transmitters and Nano for the receiver perhaps.
How will you power each module? Small li-po packs could be good, but what if you need to recharge them? Also, they will give only ~3.7V, so maybe avoid using 5V Arduino. Digispark boards are very cheap, but may only run at 5V.
I understand you are looking to guard your equipment from theft with a technical solution. Have you seen any commercially available solutions that you might want to reproduce?
My personal experience in "nature" is animals are everywhere, and trees move when the wind blows. If you use a motion detector, prepare for it to always be alarming. If you select an infrared detector (warm bodies), prepare for all-night alarms.
The lack of technical solutions probably is not be because no one wants to help. You can see thousands upon thousands of cases of technical help being given here, for free, every day, all day.
I think the "tin-can" solution might be the best here, by attaching an alarm to each piece of equipment. Using tech, you could have a "knock" sensor to register any movement. Pair that with an ESPNOW wifi network and you can have it all piped to the Arduino beside your bed (or maybe a smart-phone wifi).
