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. 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. 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. 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
