===== Overview =====   
Power consumption reduction efforts previously focused on sleeping the microcontroller. However, for the weatherboxes that do not use the Arduino Uno, the XBee power consumption is magnitudes larger than the power consumption of all other components on the board. So, efforts should focus on sleeping the XBee. This tutorial (http://www.fiz-ix.com/2012/11/low-power-xbee-sleep-mode-with-arduino-and-pin-hibernation/) outlines a basic method for using an external device, in this case, the microcontroller, to sleep the XBee. However, a potential disadvantage of this approach is that it may complicate two way programming efforts which require the XBee to always be on. 

===== Power Saving Algorithm =====   
   Build based on generation of weatherbox
   Initialize board struct
   Set timer configuration values
   Loop
      Reset timer flag to 0
      Increment board cycle count
      Sample Heartbeat Data
      Wake up XBee
      Transmit Heartbeat Packet
      Sample Sensor Data
      Transmit Sensor Packet
      Sleep XBee
      Sleep microcontroller for 1 second
      Wake from sleep
   End Loop
   ISR (When timer interrupts every 1 second)
      Set timer flag to 1
