HOME AUTOMATION PROJECT FOR A HANGING GARDEN WITH TEMPERATURE, AIR HUMIDITY AND SOIL HUMIDITY SENSORS, CONTROL AND PROGRAMMING FOR ESP 8266

Abstract

Information technology, as well as the Internet of Things (IoT), has continuously evolved over the past decades to the point where this field of knowledge, combined with advances in signal processing and artificial intelligence, is driving the natural evolution of process control, home automation through cloud-based mobile applications, and automation as a social reality of the future. Smart irrigation systems integrated with automated control and IoT represent a sophisticated and up-to-date way of using water resources more efficiently, and this variety of applications can be used in urban projects. The present project aimed to automate a vertical garden using an ESP8266 microcontroller to monitor environmental conditions and control irrigation. The system was applied to a vertical garden with three rows of plants, each having its own soil moisture sensor. A single DHT sensor measured the temperature and humidity of the environment near the garden. A single pump and relay system controlled irrigation for all rows simultaneously, continuously managing all lines. This study determined the optimal water supply required for the rows without waste, using a pump automatically triggered by the controller, taking into account useful reference values from previous academic works. As a result, a more effective and intelligent irrigation system was developed, capable of saving time, reducing water loss that occurs with manual watering, and improving the efficiency of garden irrigation systems through the proper use of simple and low-cost automation.
