Here's the answer.
Logs over 65,000 log records (based on logging data from 4 soil sensors and 2
temperature sensors)
o Approximately 45 days of logging when sampling every minute
o Over a year of logging when sampling every 10 minutes
Logs over 116,000 log records if only one sensor is logged
o Approximately 80 days of logging when sampling every minute
o Over two years of logging when sampling every 10 minutes
Battery life using standard alkaline batteries will be more than adequate for
these logging time frames under ideal conditions. In extreme conditions battery
life will be reduced but should still be adequate to provide full logging capacity.
And for fun.... The maximum power draw is 18mA.
Sleep power draw is 6ľA
