Efficient Datalogger with Sleep and Wake Features
Check out one of our latest projects – a super efficient datalogger using the DS3231 Precision RTC Featherwing from Adafruit.
This device reads and logs temperature, humidity, and battery voltage. Afterwards, it goes to sleep only to wake up at a preset time to do it all over again, ensuring you get the most out of your battery!
During our tests, this datalogger had running current of 10mA-27mA when active and 610uA when asleep. It can last for MONTHS with an output of 12-24 logs per day!
