Design and Implementation of IoT based Automated Tomato Watering System Using ESP8266

Abstract

Tomatoes need a proper watering system in order to grow and provide optimal yields. The factors that must be considered in watering the tomatoes are soil moisture and air temperature. The soil moisture needed for planting tomatoes is between 60% to 80% with a temperature rate between 24 to 28 degrees Celsius. We propose to implement an IoT based agricultural technology innovation to address the problem of precise watering system based on soil moisture and air temperature rate, which can be controlled remotely via internet connection. This system was designed and assembled using ESP8266 with soil moisture sensor and DHT11. This system was also programmed to be controlled using the Telegram Messenger application. The data read by the sensor could be seen through the Telegram Bot and do watering the plants automatically or manually. Based on several experiments conducted in this study, the system could do watering as well as maintain and control soil moisture and air temperature properly. By using this system, it will be easier for farmers to control and maintain tomato plants from anywhere and anytime through the Telegram Messenger.

Design and Development of Smart Agricultural Greenhouse

“…The test results of the smart greenhouse are presented in Table 1. The findings revealed that the heating and watering of greenhouse crops can be done through automation and smart process, which is further confirmation of the researches carried out by Goap et al (2018) and Nurhasanah et al (2021). The increment observed in the greenhouse air temperature during the test running period can be linked to the external atmospheric conditions.…”

“…The temperature, soil moisture content and soil nutrient level of the greenhouse environment will be programmed according to the environmental requirement of the intended planted crop inside the greenhouse. According to Nurhasanah et al (2021) reports, most vegetables and fruits require soil moisture content that ranges from 60% to 80% and environmental temperature that ranges from 240°C to 300°C. Environmental conditions outside the optimal range of a crop severely affect its production and performance (Ma et al, 2016;Xue et al, 2017;Awad et al, 2022).…”

“…Though some scientists have developed smart systems for agricultural production activities (Goap et al, 2018;Ogidan et al, 2019;Nurhasanah et al, 2021), related literature starch reviewed that there is not integrated smart greenhouse that can monitor the soil moisture, air temperature and quality within the green house. Therefore, this research was aimed at developing a prototype of smart greenhouse where the soil water and nutrients content, together with the air temperature can be closely monitored for the benefit of crops production.…”

IoT Based Monitoring and Control System of Siam Banjar Orange Plants using Fuzzy Logic Control

“…Numerous solutions have been developed to help the farmers improve the plant watering process [4]- [6]. Nurhasanah et al propose implementing an IoT-based agricultural technology innovation to address the problem of a precise watering system for tomato plants [7]. Codeluppi [8] presented lowcost and modular IoT solutions for monitoring and controlling vegetable plants.…”

Design and Development of an IOT based Plant Growth Monitoring and Management System for Indoor Farming

“…The data is also used to manage the plant watering and fertilization processes. rate, which can be controlled remotely via an internet connection [5]. Hicham Megnafi et al developed a solarpowered watering system that measures soil humidity and ambient temperature to determine optimal watering conditions [6].…”
