6. Overall Design
The project comprises of three modules:
 Embedded Module
 Desktop Application
 Web Application

7. Embedded Module

8. AT89S52 Development Board

9. Features :
• 8 bit microcontroller that supports 8K Bytes of In-System
Programmable (ISP) Flash Memory
• 256 bytes of RAM
• Operational Range - 4.0V to 5.5V
• Used two ports( Port 0 and Port 3) as Output Ports and two
ports(Port 1 and Port 2) as Input Ports
• LCD feature provides on checking of values

10. XBee Pro S2

11. Features :
• Low-cost, Low-power, Wireless mesh network standard
• Supports range of 1500 m ( line of sight)
• Operating Voltage – 3.0V to 3.4 V
• Free Testing and configuration software (X-CTU Software )
• Contains three different device types : coordinator, router, and
end device

12. Design Models

18. Schematic Design

19. Experimental Results
 Created a fast response WSN for checking the quality of drinking water
 Temperature, pH and Turbidity are found using ‘Real time data acquisition’
 ZigBee mesh network makes ‘Real time data acquisition’ possible
 Desktop App allows the local admin to administrate the respective local
station
 Web App allows the Central Admin to administrate all the local stations
registered to it, from any remote location

20. Performance Evaluation
 Desktop App
• Compared to C/C++, Java is slower . But Java is high on security
• Memory leakage in Java is minimal
 Web App
• Slow in the first run after compilation. Faster in the subsequent executions
• JSP allows Java code and certain predefined actions to be interleaved with static web markup
content, with the resulting page being complied and executed on the server to deliver a
document
 Embedded Module
• 8KB space constraint in ROM
• Optimised code is embedded

22. Contribution of the Project
 Social relevance – the project finds its application in examining the ‘water
quality’, an important factor as far as, irrigation, domestic purposes etc…
are concerned
 More parameters can be taken into account, thereby further improving
the process of examining the water resource
 The idea of ‘remote data acquisition’ has a wide range of applicability. For
example – in weather forecast in aero planes, traffic monitoring system
etc…
