Development of IoT Devices for Drinking Water Quality Monitoring Systems

To know the quality of drinking water in Indonesia, conventional method, which must be done by testing water samples in a water testing laboratory which not everyone knows where it is and takes quite a long time to get the results. For this reason, it is necessary to design a drinking water monitoring system prototype in a water tank that is easy to use using IoT technology. Sensors are used to retrieve water quality parameter data in real time and then the ESP32 microcontroller which is equipped with a WIFI module will send data to a database server which can then be downloaded and displayed via an application. The parameters monitored in this work are the pH value, electric conductivity, temperature and turbidity, following the standards of the Indonesian government for drinking water. The test results show that the prototype is working according to the design.
