Abstract :
In daily basic life, organism specialy human can not life without water.
Quality monitoring and control is done manually which takes a lot of time. This
often causes humans not think much about the cleanliness factor of the water that
they use, so in the end it can cause several new diseases and problems. To solve
this problem we need an innovation and one of which is utilize the internet
network to monitor and control water quality in water reservoirs to keep water
conditions clean and safe before use.
In this study case the authors made an idea of "Design and development
Of Water Quality Control In Water Shop Based On SYSTEM INTERNET OF
THINGS /(IoT)". This design device uses a pH-4502C sensor and a turbidity
sensor as a water quality detector and NodeMCU ESP 8266 which is used as a
wifi module in the process of sending data from the design device to the blynk
platform as a server.
From the results of testing data an average of the accuracy of the design
measurement device error are 3% using digital pH as a comparison measure and
2% using litmus paper as a data approach for the pH value achieved. The
conditions of water can be monitored and controlled in real time using the blynk
platform which functions as a server.
