Actually it only consumes 150uA when it's active so if it's just doing one reading a minute then it'll be closer to the deep sleep current which is 5uA or so.

There is an awesome library (https://github.com/boarchuz/HULP) which makes using the ULP much easier so that things like software i2c and ADC multisampling are trivial.
