SLIDE 20

XBee Wireless Module

  • Self-healing, self forming network
  • All nodes will have the destination address set to the

address of the control system node

  • Range on trashcan: maximum of 90m
  • Range of control system (PRO): maximum of 1.6 km
slide-21
SLIDE 21

Power Supply

  • The power supply subsystem will consist of the utilization of

power from a solar panel as well as a central battery terminal.

  • The battery terminal will efficiently be charged by the solar

panel.

  • Battery terminal will use Nickel Metal Hydride (NiMH)

batteries.

Battery Selection

  • Battery selection very important as to ensure the overall

design receives consistent adequate amount of power to perform correctly.

  • Top 3 batteries as follows with a few specifications provided
slide-23

*Solar panel powered automatic charger with automatic cut off reference circuit *Circuit design concept

slide-25
SLIDE 25
  • Ordinary operation while charging battery
  • Cutoff capability
  • Feedback capability while performing correctly

Serial Communication

  • The wireless node is connected by USB to the control system
  • The data being received is read straight from the serial port
  • Parsed to distinguish between different parameters:
  • TrashcanID
  • Status
  • Latitude
  • Longitude
  • The parameters are used to update

the database of the newly received information

Issues

  • Xbee shield isn’t able to communicate on original PCB
  • GPS has too high of a current draw and causes it to interfere

with the PING sensor

  • PING sensor does not read microfiber material
  • IR sensor does not read well in direct sunlight
  • Solar Panel needs to be in direct sunlight to work efficiently
