How many sensors do I need?

Most of our insulin users, for example, have two sensors: one for their insulin in use, that they carry around with them during the day, and one for their stock in the fridge at home. You might want to use only one sensor to put with your medications in your fridge and occasionally take with you in a cool bag, or you might also want to use two sensors to check on meds both at home and in your office fridge.
