Abstract

This paper presents the design and implementation of fuzzy logic model for control the humidity of Cactus plant which is integrated with an automatic drip irrigation system. This proposed system not only can control the humidity but also can give an information about the humadity of Cactus using the Node-RED-based MQTT protocol. This fuzzy modeling has two input variables and two output variables. The input variable was come from two sensors, namely the soil moisture sensor as a sensor for measuring soil moisture, and the DHT22 sensor as a measure of air temperature in Cactus plants. The output variables are the duration time of drip irrigation and duration time of lights on. In this research, we use a case study of 28.3oC for temperature and 60% for soil moisture as an input. The simulation shows that the output of fuzzy model are 0 seconds for the duration of the watering time and 3 minutes for the long duration of the lamp on. Furthermore, the proposed system shows the same output with the simulation. This result indicates that the fuzzy model for controlling the humidity of Cactus was successfully implemented in our system. The monitoring system in this system also gives a good performance. These results concluded that the proposed system already running well to control the humidity of Cactus plant.
