Building a Courtyard-environment-monitoring System Based on Internet of Things Architecture

Abstract

With the rapid development of technology, people are living a faster pace of life as they seek a better quality of life, and this has led to various stresses. Horticultural therapy and city greenification have emerged in recent years as countermeasures to relieve the stresses of a busy life by using plants to beautify the townscape. In this study, we used NodeMCU as a master control board and sensing modules to detect the temperature, humidity, illuminance, soil moisture, and rain in a courtyard environment. An ESP8266 Wi-Fi chip was used for the wireless transmission of data and the control of loads of sprinklers, fans, plant lights, landscape lamps, and step motors for awnings to implement the system, which was based on the concept of the Internet of Things (IoT). This system uses fuzzy control for automatic control and sets up a rule base in accordance with the effects of current air humidity, temperature, and soil moisture on the plants in the courtyard to control the sprinklers, fans, and plant lights to make the environment suitable for plants. The automatic control and network techniques are expected to enable people to enjoy horticulture from their homes without any additional burden.
