Data measurements are sent via SMS at selected time intervals, such as daily weight change, exterior temperature, humidity and battery voltage.
Settings can be done via sending SMS:
1. Writing at eeprom the cell phone number that SMS will be send, with SMS text NEW
2. Changing time of rtc, with SMS text TIME #hour*minutes
3. Resetting the cell load to zero, with SMS text TARE
RTC controls (shuts off) powering the circuit, so the consumption is only 2mA (when not sending SMS)
The project is ready for real - conditions testing.
