Automatic Temperature and Humidity Control System for Tarantula Terrarium Using Fuzzy Logic Algorithm

Temperature and humidity play vital role in most invertebrates. Without proper temperature and humidity, invertebrates are prone to bad molt which can lead to injury and death. Due to different needs of invertebrate, having a system that can control wide range of temperature and humidity can help to encourage the growth of captive bred tarantula and other invertebrates. The goal of this study is to create a system that can solve this problem with the use of fuzzy logic. Incorporating fuzzy logic can help in controlling the parameters as consistent as possible. Corresponding devices will turn on and off to control the temperature and humidity. This includes fan, water pump and heatlamp with DHT11 as a sensor for temperature and humidity. Without fuzzy logic, the system might flood the terrarium or heat too much that would kill the tarantula inside. Although the system is limited only in controlling temperature from 25˚C to 36˚C, the data obtained from the automated system showed better parameters compared to not using the system.

I. Introduction

Terrariums is a glass enclosure which is used to create tiny ecosystems for plants and animals to offer sustainable and efficient development throughout the year. Problems arise when taking care of exotic plants and animals due to the changing environmental conditions affects the growth of a plant and animals [1]. Rainfall, temperature and humidity are factors that vary in different places and significantly affect environmental conditions. And to really succeed with any plant or animal, you must give it an environment to which it is adapted. Because stagnant air is bad for plant and animal growth in a terrarium, air circulation during the day is essential. Bringing in outside air may vary the temperature inside, affection the subject’s growth. As a result, it’s critical to keep the terrarium environment consistent and predictable.
