Remotely Operated Vehicle (ROV) Robot For Monitoring Quality of Water Based on IoT

Water is a very important element for humans. Clean water needs are always increasing, but the supply is running low due to water pollution. Various factors can affect water quality, including pH, turbidity (NTU), and substances that are dissolved in water (PPM). Therefore, water quality monitoring must be carried out quickly to determine the level of water quality that is around. By utilizing technological developments such as robots and internet of things monitoring water can be done in real time. In this study a robot system was developed to carry out water quality monitoring based on internet of things. This system uses a microcontroller, Arduino. The developed robot system is controlled by using a remote controller. The monitoring system developed uses a pH sensor to measure pH, a turbidity sensor to measure NTU, and a TDS sensor to measure PPM. To monitor, cloud server is used as a data viewer and data store. Cloud service used is Thingspeak. From the results of testing the robot system, the robot can be controlled properly, and the robot can be controlled to a distance of 140 meters with a robot speed of 0.46 km / hour. From the results of testing the monitor sensor, sensor can work well with an average speed of sending data for 30 seconds.
