Abstract

In general, plant growth will be disrupted if the environmental temperature is not suitable, even the plants will be damaged, which can cause a decrease in quality and quantity. Problems that often occur and are difficult to avoid include temperature and humidity conditions on agricultural land. Therefore it is necessary to do handling to be able to minimize the occurrence of damage that can occur in the land caused by environmental influences. This study aims to design a temperature and humidity monitoring system based on the Internet of Things (IoT). The research was carried out by designing electronic circuits from monitoring systems, hardware, software, and testing the systems that had been made. Technology supported by the use of DHT22 sensors can read temperature and humidity data in real time. Based on the research results, it was found that the DHT22 sensor used worked with the best accuracy on day 21 with an error percentage of 0% and the worst accuracy occurred on day 31 with an error percentage of 18.5%.  Keywords: Internet of thing,Humidity,DHT22 Sensor,Air temperature.

Abstract

Plants receive water from the fog irrigation system in the form of tiny, mist-like water particles. Currently, irrigation technology has advanced, nurseries can be automatically irrigated. In this research, the ESP32 microcontroller is used to create the electronic circuits for the automation of the fog irrigation control system in a mustard green nursery. This study's methodology combines direct field observation with an experimental or trial approach. Water flow (ml/minute), water use efficiency (%), plant height (cm), number of leaves, and scheduled fog irrigation system performance are among the measured parameters. In this investigation, four different treatments were used: manual irrigation using a watering can, two-time, three-time, and one-time irrigation. All is going according to plan with this mist watering system. With an average height of 4.58 cm and an average number of leaves of 3.24, the mist irrigation system had the highest water use efficiency of 77.35% during the test. It was also found that mist irrigation produced the highest amount of mustard leaves in the three-times-per-day treatment. Keywords: ESP32, Fog irrigation, Green mustard, Nurseries.
