Perancangan Sistem Pengukuran Kadar Kelembaban Hidroponik Menggunakan Analisis Fuzzy Berbasis Mikrokontroler Nodemcu ESP8266 dengan IoT (Internet of Things)

Abstract

This research discusses monitoring humidity levels wirelessly using a fuzzy method based on the ESP8266 nodemcu microcontroller which is carried out on hydroponic plants. The components used in this circuit are LCD which functions as a display medium by utilizing liquid crystals as the main display object, DS18b20 humidity sensor which functions to detect temperature changes in the surrounding environment and then converts the temperature measurement results into electrical quantities, 5 Volt USB power as a voltage source. , the nodemcu ESP8266 microcontroller functions to run application programs directly on the module, making it the brain of various IoT projects and wireless systems and the fuzzy method is one of the components that form soft computing. The results from the DS18b20 sensor on the system can run well and produce values that are not good or good on the sensor. The accuracy level of the DS18b20 sensor with standard DS sensor tools is 97.42%. Through these results it can be concluded that the DS18b20 sensor value is close to the standard DS device and this system can monitor or control humidity in real-time. From these results, users hope that it will be easier to control humidity remotely connected to the IoT application.
