  • New technology allows for it to connect even in low cellular service areas.
  • Includes rechargeable battery that lasts 2-4 weeks between charges when you don't have constant power.
  • Rechargeable by USB, solar panel or 12 VDC
  • Can communicate with "Sensor Nodes" to allow for additional sensors to be placed throughout the sugarbush.
