Water Quality Monitoring System in Autonomous Underwater Vehicle Based on Internet of Things (IoT)

Water is a resource needed by mankind in many ways. Water quality is comparable to the benefits of water so that if the water quality decreases it will affect who will take advantage of it. Therefore, it is necessary to monitor the water quality to see the condition of water quality. For this purpose, this monitoring uses Autonomous Underwater Vehicle (AUV) that can move automatically. AUV is equipped with sensors such as pH sensors, total dissolved solids sensors, dissolved oxygen sensors and temperature sensors as water quality determinant parameters. The water quality obtained on the surface of Lake OPI Jakabaring at a depth of 9.45 cm is in normal condition where for the sensor value is: pH = 6.23; temperature = 33.45 °C; DO = 2.97 mg/L; TDS = 40.64 ppm and at a depth of 110.73 cm is in very good condition where for the sensor value is: pH = 7.65; temperature = 29.92 °C; DO = 5.14 mg/L; TDS = 29.33 ppm. Then it is done sending IoT-based data by using esp8266 module as a tool to send data to the website. The website can display the water condition that is monitored according to the parameters and each sensor.
