OpenWeatherMap simple GSM-based autonomus sensor

OpenWeatherMap simple GSM-based autonomus sensor At start of this project we have developed a simple autonomus sensor.

= Capabilities and features =


 * GSM \ GPRS \ EDGE channel directly to openweather map API. GSM module  WISMO228.
 * 5V - 20V wide power range, LiIon battery charger ( 1A current limit )
 * Solar power from 6..12V panel is OK
 * Sensors: Temperature and Pressure - H03M, Temperature and Humudity - SHT1x
 * Data in output: sersors + input voltage, battery voltage, charge current
 * Settings and control by SMS
 * CPU - Atmel AVR xMega256A3
 * Memory: up to 100 all sensor measurments, store messuments in case of data transfer failure
 * Several data session control for celluar bill optimization ( constant, on-demand, on-request)
 * Optional (and unsupported in FW) GPS on uBlox5

= Software =
 * AVR Studio 6 project
 * FreeRTOS based
 * Pure C

= Hardware =
 * Sheamtic and gerber files for PCB avaliable
