Arch GPRS: Is it possible to use Grove Temp/hum sensor??

Hi again

I have placed a Grove light sensor, and a Grove Temp/Hum sensor in the jar, together with the Grove Shield. All works fine, when connected via USB. But as soon as it is battery powered, the Temp/Hum sensor is not giving any output....

Can anyone explain that??

Elaborate more...
I've not used the Grove stuff, but, briefly looking over them, neither the shield or the sensors have a battery input and the shield's wiki specifies its operation at 5v... So, how do you have the battery connected? What voltage is the battery? What voltage are you getting across the humidity sensor's power pins? What Arduino board are you using?
