The method used is not based on flight time or signal Doppler shift, but on the signal strength (RSSI - Received Signal Stren- gth Indicator) using a probability model (the location with the highest probability is selected). The Sigfox geolocation service will evolve in 2017 to increase its accuracy by using machine learning technology.</p><h3 >Accelerometer</h3><p >Another key technology is the micromachined accelerometer inside the MMA8451 device: an I2C interfaced sensor that our project uses to detect movements and trigger the communication with the Sigfox network. Thanks to the low power modes of SAMD21 and Sigfox technology, expect this project to run for several months on a pair of AA Alkaline batteries.</p><h3 >Components</h3><figure><img src=https://projects.arduinocontent.cc/e3f3a549-960f-4220-82f8-2e00deba743d.JPG /><figcaption> </figcaption></figure><h3 >Build it</h3><p >Connect the 3 axis to  the MKR FOX 1200 as shown: </p><div id="gallery"><img id="gallery" src=https://projects.arduinocontent.cc/8d8595e0-ee54-4743-9bba-c4115a3fb2d1.JPG /><figcaption> </figcaption><img id="gallery" src=https://projects.arduinocontent.cc/db6e44aa-bf40-40b3-8567-5af55615660d.JPG /><figcaption> </figcaption></div><p >Connect a jumper between pin 14 and pin 0: </p><figure><img src=https://projects.arduinocontent.cc/8edca603-4190-4c97-be11-6ea6f974f83c.JPG /><figcaption> </figcaption></figure><p >Put in a nice box: </p><div id="gallery"><img id="gallery" src=https://projects.arduinocontent.cc/d06729d0-8b8d-4113-988d-829962aaab89.JPG /><figcaption> </figcaption><img id="gallery" src=https://projects.arduinocontent.cc/5886d29d-7ee3-468f-8570-2b3d5f487d6b.JPG /><figcaption> </figcaption></div><p >Place the box inside the car:</p><div id="gallery"><img id="gallery" src=https://projects.arduinocontent.cc/dd28ac56-ea8c-4f7d-ad1d-79de84e83d05.JPG /><figcaption> </figcaption><img id="gallery" src=https://projects.arduinocontent.cc/1d77824e-be25-43b0-91ba-681ad8910fde.JPG /><figcaption> </figcaption></div><h3 >How it Works</h3><p >Once the movement sensor triggers, the MKR FOX will send an alert message with the coordinates taken from the network.</p><h3 >Software</h3><p ><span >On software side, if you haven't done yet, register your MKR FOX 1200 by following the example </span><a href="https://www.arduino.cc/en/Tutorial/SigFoxFirstConfiguration">here</a><span >.</span><a href="https://www.arduino.cc/en/Tutorial/SigFoxFirstConfiguration"> </a></p><p ><span >Then go to the Sigfox backend </span><a href="https://backend.sigfox.com/">https://backend.sigfox.com</a><span > and configure the callback as follows:</span></p><figure><img src=https://projects.arduinocontent.cc/7f94c36f-2545-4710-b8a5-dfe0568a73a3.png /><figcaption> </figcaption></figure><p >Change the recipient with your email address.</p><figure><img src=https://projects.arduinocontent.cc/a35e03fe-9e76-46d8-825e-57def5b785c6.png /><figcaption> </figcaption></figure><p ></p>
