3. WATER QUALITY MONITORING SYSTEMS
• Integrated systems that collect and analyze water quality data
• Consist of sensors, data loggers, and communication technologies
• Sensors measure various parameters like pH, temperature, turbidity, and
conductivity.
• Data loggers store and manage the collected data.
• Communication technologies transmit data to centralized platforms for analysis

4. WHY IS WATER QUALITY MONITORING
IMPORTANT?
• Protects public health by detecting harmful contaminants
• Enables proactive measures to address water quality issues
• Provides data for effective water treatment processes
• Promotes water conservation efforts

5. OBJECTIVE
• The main objective of water quality monitoring is to assess the health and safety
of water resources for various purposes such as drinking, recreation, and
ecological balance.
• It involves measuring various physical, chemical, and biological parameters to
ensure compliance
• regulatory standards and to identify any potential risks or contaminants
present in the water.

6. TYPES OF WATER QUALITY MONITORING SYSTEMS
• Fixed Monitoring Stations: Permanently installed at specific locations,
providing continuous data
• Portable Monitoring Kits: Compact and user-friendly for on-site water
quality assessments
• Remote Monitoring Systems: Utilize drones or satellites for large-
scale water body monitoring

8. PH sensor: The pH of a solution is the
measure of the acidity or alkalinity of that
solution. The pH scale is a logarithmic scale
whose range is from 0-14 with a neutral point
being 7.
Flow sensor: Flow sensor is used to
measure the flow of water through the flow
sensor. This sensor basically consists of a
plastic valve body, a rotor and a Hall Effect
sensor.

9. Turbidity sensor: Turbidity is a measure of the
cloudiness of water. Turbidity has indicated the
degree at which the water loses its transparency. It is
considered as a good measure of the quality of water.
Turbidity blocks out the light needed by submerged
aquatic vegetation.
Temperature sensor: Water Temperature
indicates how water is hot or cold. The range
of DS18B20 temperature sensor is -55 to +125
°C. This temperature sensor is digital type
which gives accurate reading.

10. Arduino Uno: Arduino is a microcontroller board
based on the ATmega328P. It has14 digital
input/output pins (of which 6 can be used as PWM
outputs), 6 analog inputs, a 16 MHz quartz crystal, a
USB connection, a power jack, an ICSP header and
a reset button. It contains everything needed to
support the microcontroller.
Wifi module: The ESP8266 WIFI
Module is a self contained SOC with
integrated TCP/IP protocol stack that
can give any microcontroller access
to your WiFi network.

11. Feature Pure Water Polluted Water
Composition H2O only H2O + impurities
Impurities None Various pollutants
Appearance Clear Can be cloudy, discolored
Safety for drinking Generally safe Not safe

12. 𝑊𝑄𝐼𝐴 = 𝑤𝑖𝑞𝑖 𝑖=1 𝑛 𝑖=1 𝑤
𝑤𝑖 is the relative weight of the ith parameter and 𝑞𝑖 is the water quality
rating of the ith parameter.
𝑞𝑝𝐻 = 100 [(𝑉𝑝𝐻 – 7.0) / (8.5 – 7.0)]; where 𝑉𝑝𝐻 = observed value of pH

13. • Early detection and prevention of water quality issues
• Improved water treatment processes
• Enhanced public health protection
• Sustainable water resource management
• Cost savings in the long run

14. CONCLUSION
• Water quality monitoring systems are vital for safeguarding our water resources
• By providing real-time data and enabling informed decision-making, they play a
critical role in ensuring public health and environmental well-being
• Continued advancements in technology promise even more effective and
accessible solutions for the future.
