Stalker v2 Sleep mode and RTC wakeup

Hi,
what is the code to put Stalker v2 into sleep mode and to wake it up by RTC module each lets say 20 minutes to messure and log data?
Do you know what is the power consumption during sleep mode?

I plan to use 6Ahr Li-Pol battery and log data each 20minutes from I2C SHT15 sensor. Do you think it might run for 2 months like this?
:nerd:
Thanks for reply

I think it will run more than 6 months, if it has a solar panel :smiley:
we have a test here:http://www.seeedstudio.com/blog/2011/02/23/could-seeeduino-stalkers-survive-the-day-after-tommorow/
I am sorry, we do not have a to wake up the stalker by RTC yet, we will work on the code and test the power consumption.
Thanks
Albert
