My experience with Arduino is limited, especially when it comes down to Wi-Fi.
I wanted to place down a sensor that triggers once someone gets close to a door.
It should ignore people in front of the door but someone who touches the door should be recognised.
A single ray that checks only one vector or a small area in front of the door would be enough. I don't need any large spreaded rays that check whole areas.
Once that happened, my Arduino shall send a notification to my computer, which then gives me an audio signal. My computer has a Wi-Fi connector, can I hook up an application to receive these signals?
Additionally, my Arduino shall run on a battery (chargeable would be cool).
Therefore, getting a warning once the battery runs low, would be neat (and needed)!
Sadly, searching on the internet gives me many results of all kind of products, which renders me confused :o
I assume, I need following things:
An Arduino (Which one? Uno?)
A movement sensor
A Wi-Fi-transmitter for the Arduino
A battery for the Arduino
A small Breadboard
And a fancy box to cover it all up. Haha!
The budget should not go too crazy. Moreover, I have no feeling for these kinds of products, are 25$ too low?
It would be great if someone could help me out (and even list products).
Thanks for taking your time to read my thread : ) !!
I don't know how you will pull off the "touch the door" sensor. A metal door might offer some hope, but if it's painted, not so easy. You may nee to rethink your sensing trigger. Whatever you do to sense a door touch is going to push you way out of your budget range.
Assuming you can work that out, there are now some combined very cheap wifi units available which are compatible with Arduino, namely the ESP8266. That plus the Nano version of an UNO should set you back less than six dollars. Until you work out the door sensor part of this, you can't scope the battery requirement.
I think the way I described the sensor went a bit out of hand, because everything I need is just a usual movement sensor. By saying "touching the door", I tried to describe how someone should be close to the door. Since I don't want it trigger when people just walk on the floor in front the door.
Is there a shop where I can buy these Arduino products? I find so many different versions, often not even Arduino ones. : /
Edit:
Are the Genuino Products the same?
Edit 2:
I found out, that the Genuino ones are the name for everywhere but the USA.
The store does not seem to have Genuino Nanos though, is a Micro the same?
Sadly, the store does not have the pir sensor. Where would you get these items?
