The document describes a proposed real-time water quality monitoring system using a ZigBee-based wireless sensor network. The system would use sensor nodes equipped with sensors to monitor temperature, turbidity, and pH levels. The sensor data would be transmitted wirelessly via ZigBee protocol to a base station and online database for real-time monitoring and reporting on water quality. The system aims to provide low-cost, flexible, and reliable remote water quality monitoring.

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
