Develop IOT device to monitor temperature and position

Build IOT device to monitor temperature and position.

For the first prototype, use comercial board (like Arduino, Linkit One, ESP, etc) with

- DS18B20 temperature sensor


- GSM/3G to send data

- WiFi (optional)

- Battery

Data will be send to our server, we could discuss best way and the periodic to send it (better battery life versus accuracy)
