This project was created on 06/01/2017 and last updated 2 years ago.

Description

The plan is to power down the gps and gsm modules and keep the arduino in sleep which is woken up by a interrupt signal from the accelerometer, this will turn on the gps module and watch for movement. Periodically the arduino will wake the GPS module to confirm it hasn't moved from within a configurable distance. Movements will be sent via SMS and posted to a logging service (TBD)

Components

  • 1 × SIM800L 2G GSM module with GPRS
  • 1 × NEO-M8N GNSS Module
  • 1 × ADXL345 Accelerometer module with interrupt output
  • 3 × RT8272 Buck regulator module
  • 1 × Arduino pro micro Arduino

whats the plan if GSM network is not available ? write to an SD card ?

  Are you sure? yes | no

ximon wrote 09/25/2017 at 13:04 • point

I was originally planning to just use the latest location when a connection had been established, but it would probably be useful to keep a log of past locations. SD should be easy enough to interface to
