Abstract
System consists of a WSN, with a number of sensor nodes with networking capability for monitoring
Remote data acquisition
Parameters considered include – temperature, turbidity and pH
Reduces the overall cost, increases the flexibility
ZigBee-high transmission power with relatively low power consumption
Overall Design
Overall block diagram
Overall Design
The project comprises of three modules:
Embedded Module
Desktop Application
Web Application
Embedded Module
AT89S52 Development Board
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
XBee Pro S2
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
Design Models
Schematic Design
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
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

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…
Thank You…
