Abstract

Water that suitable for consumption must comply with several biological, chemical and radioactive
requirements. The majority of people not understand the quality of the water they consume, most people only recognize
clean and dirty water, without knowing the suitability of this water. Because not all substances contained in water
can be seen with the naked eye, so it will be difficult to know whether the water is in accordance with the quality of
drinking water or not. This study was aimed at monitoring several drinking water quality parameters in the form of
pH (6.5 - 8.5), Turbidity (<5 NTU) temperature (22 ℃ - 27 ℃) and TDS (<500 ppm) using pH sensors, turbidity
sensors temperature sensors and TDS sensors, and Ultraviolet light as an inhibitor of bacterial growth. The resulting
data is executed by NodeMCU 8266 and forwarded via IoT to be sent to the server and forwarded to the application
automatically. The results of the pH sensor readings show a reading accuracy of up to 98.36%, the temperature sensor
the reading accuracy reaches 96%, the turbidity sensor has an accuracy level of up to 90.1%, while the TDS (Total
Dissolve Solid) sensor has an accuracy level of 95, 16%. Water from the filtration of the water filter can be categorized
as suitable for consumption accordance with drinking water standards in the Decree of the Minister of Health No.492
of 2010.
