/*
This code is refer to the example of PachubeClientString of Arduino
libraries and example of GPRS Shield, it is only a test code for the place
with stable GPRS signal.
Different countries may use different APN name, this example is work in China,
we use APN name of CMNET, please do not use it in your country.
Circuit:
* Battery positive port attached to analog in 0
* Temperature&Humidity sensor attached to analog in 5
* GPRS Shield attached to digital 7,8
