Sometimes we want our projects on, but sometimes we want to turn them off for a while to save power. The SparkFun Nano Power Timer will run while only consuming minimal power (approximately 35nA) and turn your project on after a set amount of time. When you are done polling your sensors, posting data to the web, writing to your logger, or planning world domination, your microcontroller can tell the Nano Power Timer to turn off the power. No more running your microcontroller all day when you only want to read the ambient temperature once per hour.
