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

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

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

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
