Water Quality Monitoring And Domestic Usage Management System

Abstract

Water resources are getting scarce and unreliable as time progresses. It is essential to identify the quality of water. This project includes necessary hardware and software tools that provide a reliable mode of measurement of water quality and usage with a user- friendly mobile application interface. The hardware model is designed with the ESP-8266 NodeMCU as the microcontroller unit. This module is capable of connecting to a network and transmission of data over the internet. A temperature sensor is utilized to screen the temperature of the water.DS18B20 is the temperature sensor that is being used because of the reliable library files available. A pH sensor is used to measure the pH of the water in the motor. The pH sensor has been explicitly worked to gauge the pH of the fluid. The flow sensor is utilized to decide the measure of water moved from engine through the sensor.The software tools include the Arduino IDE for programming the ESP8266 NodeMCU. Google Firebase is used as the cloud service to transmit and store the sensor data. Firebase is known for its speed and security and hence, it has been chosen over other cloud services. A mobile application on android operating systems has been developed to view the output from anywhere over the internet. The app is linked to the firebase cloud service and retrieves data at very high speeds. Various data like the amount of water used, water level in the tank, pH of water and temperature of water is measured, transmitted to the cloud and retrieved on to the mobile app for continuous monitoring. The app enables the user to monitor the sensor values from any place at any time. The app alerts users when they usage limit exceeds. The users can also know the amount of water used in exact litres. Current systems prove to be very costly and bulkier. This system is a simple combination of hardware which can be neatly packed as a product. The novelty lies in the reduced power consumption of the system and a secure user interface to display the data in the form of a mobile app.
