GPS, SMS, SD-card, acceleromomter, XYZ, external batterry


I was looking for a Device guideline to include functionality like:

Position sampling (1, 2, 4, 8 sec, 1, 5, 10 , 30, 60 mins)
XYZ acceleromometer (1, 2, 4, 8 sec, 1, 5, 10 , 30, 60 mins)
Barymethric pressure (1, 2, 4, 8 sec, 1, 5, 10 , 30, 60 mins)
Onboard Storage (Micro SD)
SMS/GPRS capability

Exteral battery for prolonged life (3-4 months)

In the end i want fit the setup in a rugged case and eventually Place on large Mammals (e.g. domestic sheep) for analysis of movement.

What hardware/software would be usable for this task?

Best regards,


Hi, welcome to the forum.

At you can find the GPS sensors and the other sensors. Writing that data to a (micro) SD card is no problem. I will require some effort to make it run for 3-4 month, but perhaps when sampling only once per minute and without the accelleration and with a large battery it could be possible.

The accelerometer requires that the Arduino is always on and continuously samples the data.
For the temperator and the baromic pressure it is easier, the Arduino can enter sleep mode, and wake up every minute to gather some data and write it to the SD card.

The common sensor for baromic pressure is BMP180, and for temperature it is DS18B20.

The SMS/GPRS is a problem. There are shields for that. I don’t know if it is in the store of at the moment. With a GSM/GPRS shield I think it is not possible to run for 3-4 moths.
