For your information:

Arduino Mega + GSM shield + PT100 + RTC

- 80 mA: Serial print of PT100 value + RTC datetimestamp every 2s
- 100 mA-120 mA: the same but with GSM module powered on

I'll see if I can get some power consumption information when tranmitting by GPRS.

Make sure your power supply is able to deliver some Amps
