Abstract :
The Internet of Things has been widely applied in several fields such as health,
engineering, security, to agriculture. The Internet of Things uses several technologies
that are combined into one such as sensors, internet connections, radio connections and
forms of network topology according to the purpose of the tool being made. With the
Internet of Things-based pH adjustment system, it will be easier for cultivators to
supervise and control directly.The research was carried out using the Arduino
microcontroller and NodeMCU ESP 8266 and using a pH meter to measure the pH level
in the air as a food source from plants. . The output of the fuzzy calculation results in
the form of a timer, which is the length of time it takes to remove an acid or alkaline
solution through a solenoid valve.Based on the research conducted, automatic water pH
stabilization has been successfully built and can be accessed via Smartphone or Laptop.
Tests using the MAPE method got a MAPE value of 8.33% with an accuracy of 91.67%
