Klx230SM-ProMini-Sim800L-NEO-6-Gps

 The fact that europe does not allow us (euro 5 etc..) to have
klx 230 sm
may offer me the time to develop a MINIMAL and effective system in case
that in the future ...i will be able to buy such a perfect (for me) motorbike!!!

Arduino Pro Mini Project.
-We need to be able to Find the gps location of our motorbike in case of bad peopling ...
-We dont need a motion/gyroscope detector(6050) because ....?...
-So we need only gps module , a sim800l and a micro processor...

Estimated cost
15 ,3AA rechargable batteries
8 pro mini
12 sim800l
10 neo6 gps
10(box,wires,solers, breadboard,pins ,on/off button)
10 for 2 relays
10 for voltage regulator @(4.1 vols)

~~~~~
about 75 euros per device....
Advantages
-Low cost (do it yourself) devise
-no yearly expenses just one sim phone card(10 prepaid euros for ...1 year?)
..to send gps loc on thingspeak
 

Disadvantages
-Too much power consumption(need minimized)
-Device must be in a well hidden place but easy to on/off and change batteries
-If device is static when motorbike runs....then do vibration damage electronics in the long run
(especially for someone on wheelies!)?
-be so stupid that you uploading this online(disadvantage for me only!)

Main concept
-Power on
-Find and Hold Gps Location (Home)
-May or may not set up as to inform user by thingspeak update or and call to some phone number
-User can go sleep
-Check every 10(or any other) minutes if we are on same location with some tolerance
-If same location...deep sleep
-If not...then first of all make a call 
-And every 2(or other to minimise battery consumption) minute
Update gps location on thingspeak
---till battery dies !!!!
Maybe better to update every 2 minutes 2 times in 10 seconds just to know also if thief is moving?

Till have my neo6 gps module...just building a sceleton....

This is like what i want but i am focusing just till Thingspeak SIM800L GPS Tracker | Send GPS Data To Server Using Arduino and PHP
