01 02
Multi-parameter
Water Testing
IoT Connectivity
03
Community Display
& Alerts
04
Data Logging &
Analysis

4. Workflow:
1. Sensors continuously measure water parameters.
2. Data processed by ESP32/NodeMCU.
3. Display safe/unsafe status locally on LCD/LEDs.
4. Push real-time readings to IoT dashboard/app.
5. Send alert notifications to community members.

5. Hardware Requirements Threats
Strengths Software Requirements
1.ESP32 or NodeMCU (Wi-Fi microcontroller)
2.pH Sensor
3.Turbidity Sensor
4.TDS Sensor
5.Temperature Sensor (DS18B20/DHT11)
6.16x2 LCD / OLED Display
7.Power supply + Jumper wires + Breadboard
1.Arduino IDE (for coding ESP32/NodeMCU).
2.IoT platform: Blynk / Thingspeak / Firebase.

7. Real-World
Impact
Helps rural & urban communities monitor water safety.
Early detection of contaminated water can prevent
diseases.
Scalable: can be deployed at public water tanks, schools,
hospitals.
