Burglary alarm Battery Driven

Projects General Guidance
1

Hi all,
This is my first post. I have a problem, I don't have a garage and I have to leave my bike exposed on the street. Often someone decide to sit on my bike, move it, play with the mirrors, punch it or even drop it on the floor :confused:

I bought an alarmed disk lock and the vandalism acts have been slightly reduced since then (at least every time it goes off they flee). However, I'd like to make my own burglary alarm with an Arduino, an accelerometer and a wifi ESP8266 to send me a notification (via app) on my phone every time a movement is sensed.

My problem is that having to place the device inside my bike seat, I need to use a small battery as power source and I cannot use the bike one for several reasons.

My loooong question is: Is there a way to turn on the Arduino with the wireless or bluetooth? I read several articles in which they managed to turn on/off leds etc. using the phone but this is not what I need because in that case the Arduino was always on to retrieve the data from the internet. What I need is more like a remote control that can turn on the device that is completely off.

Think about what your asking.

You want a Bluetooth or Wireless receiver to be working (so it can receive signals) when its actually off ?

Do you want it to automatically switch on when the bike isn't being ridden?

You could have a sleeping Arduino that wakes up every few seconds, check to see if the ignition is on. If so, go back to sleep, else stay awake and monitor for movement/vibration.

Most accelerometer chips have "motion interrupt" outputs that can wake an Arduino from deep sleep (in which it consumes negligible power) and the Arduino could then turn on a transmitter to send an alarm.

You should study Nick Gammon's excellent low power tutorial to learn how to do that.

Pressure switch and a stun gun mounted in the seat?
