REMOWZ - Realtime Water Quality Monitoring using ZigBee based WSN (Part I)

  1. 1. REAL TIME WATER QUALITY MONITORING USING ZIGBEE BASEDWIRELESS SENSOR NETWORK (REMOWZ) _______________________________________________ 14th February 2012 @nighthawknitin
  2. 2. Overview• Abstract• Introduction• Literature Survey Proposed• System• Summary of S 7• Module Split Up• Gantt Chart• References
  3. 3. Abstract• System consists of a WSN, with a number of sensor nodes with networking capability for monitoring• Parameters considered include – temperature, turbidity and pH• Reduces the overall cost, increases the flexibility• ZigBee
  4. 4. Introduction• Keeping our water resources always within the domestic usage standard is a crucial task• Industrialization .• Thus a need for an autonomous, low cost, reliable and flexible monitoring system• Project focuses on the use of multiple sensors as a device to check the level of water quality
  5. 5. Introduction• Remote data acquisition• Wireless sensor network is used to provide flexibility, low cost implementation and reliability• ZigBee – high transmission power with a relatively low power consumption
  6. 6. Literature Survey Proposed• Based upon the paper in IJET ‘Water Quality Monitoring System Using Zigbee Based Wireless Sensor Network’• Authors: - Zulhani Rasin and Mohd. Rizal Abdullah• The critical situation of the polluted natural water resources in Malaysia was the major motivation behind the project.• Low Cost, flexible system
  7. 7. System Base station (Local Admin)Embedded Module Embedded Module(Transmission Side) (Reception Side) Online Database Sensors
  8. 8. System• Sensors – Temperature, turbidity and pH• 8051 microcontroller AT89C51/AT89S52• ZigBee – XBee Pro• Base Station • Desktop Application• Online Database• Web Application
  9. 9. System
  10. 10. Summary of S 7• Completed the design phase• Determined the data flow• Designed Database required using ER Diagram• Determined the actors and designed the ‘Use- Case diagram’
  11. 11. ER Diagram
  12. 12. Use Case Diagram
  13. 13. DFDLevel 0
  14. 14. DFDLevel 1
  15. 15. Module Split Up• Desktop Authentication• Real-time Local Monitor• Generate Reports• Manage Local Stations• Web Authentication• Consolidated Real-time Monitoring• Generate Web Reports• Warnings• Alerts• Remote Data Acquisition
  16. 16. Gantt Chart•
