Water Quality and Quantity Monitoring System

This prototype was designed to provide an alternative solution to safe drinking water with the use of sensors that measure the cleanliness of the water, its pH level and provide a smart way to measure its volume in the tank. The system incorporated a mobile phone monitoring interface for seamless accessibility. This solution can be used in rural and urban areas where clean water is an essential commodity.

Description

Step 1: 3 pH sensor pins are connected to the Arduino UNO pins 5v, GND, and A0 

Step 2: 3 turbidity sensor pins are connected to Arduino UNO as G to GND, A to A1,V to 5v.

Turbidity sensor connection

Step 3: Ultrasonic sensor pins are connected to Arduino UNO as GND to GND, VCC to 5v, Echo to 4, and Trig to 5

Step 4: Bluetooth Module pins are connected to Arduino UNO as VCC to 5v, GND to GND, RXD to TX and TXD to RX.

Note: Bluetooth module pin TX and RX were removed for the code to be uploaded then reconnected after the upload to establish a connection with the Bluetooth terminal HC05 mobile App
