Just checking if someone has used ADXL345 (Or similar) sensor with Nano. I was wandering about current consumption if I can run the setup for "months" on AA batteries ?
Current consumption for 354 is said to be around 50uAmps. Power requirement can further be reduced by using "motion detection" feature of the sensor thus waking the Nano by an interrupt from the ADXL345. Anyone been there ?
What would be the minimum current load requirement achieved from Nano yet (an estimate would do)?
Secondly, if someone can share a link / provider for ultra low power sensors to work with Nano or Nano 2. I am trying to get my head around on finding ultra low power sensors in the market.
