Abstract:
Industrial wastewater can pollute the environment if not managed properly. The concept of Internet of Things (IoT) can be implemented in monitoring liquid waste content remotely and providing notifications on Android devices by communicating via the internet. To apply this IoT concept, the tools or sensors used to measure the volume of liquid waste that comes out must be able to communicate with an Android smartphone or computer. This system consists of three units: input, process, and output. The input unit consists of a Ds18b20 temperature sensor, turbidity sensor, water flow sensor, and pH sensor which are used to measure input data to be sent to the process unit. The data received by the process unit is in the form of voltage which is converted based on the formula on each sensor. The processing unit uses the NodeMCU 8266 microcontroller to process data before it is sent to the output unit. The output unit consists of a 16x2 LCD and a web server which receives data from the proce
ssing unit for display. The results of system testing show that all input, process and output units can function properly as expected. Thus, the IoT concept can be applied to remote data collection and monitoring of industrial wastewater content to ensure that the liquid waste discharged meets predetermined quality standards and does not pollute the environment.
