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.
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
