The prototype of the Greenhouse Smart Control and Monitoring System in Hydroponic Plants

Abstract

This research helps the farmers to do the humidification control and monitor the condition of hydroponic plants in greenhouses in real-time. When it comes to watching the hydroponic plants in greenhouses, the farmers usually experience difficulties because they still do it manually. Activities such as checking the temperature, air humidity, and also water quality in hydroponic plants by coming directly to the greenhouse are still ineffective. Therefore this research aims to make a smart greenhouse prototype for hydroponic plants. Smart greenhouse hardware was built based on the Arduino microcontroller, DHT11 sensor, pH sensor, TDS, DS18b20 temperature, ultrasonic, and esp8266 wifi module. The monitoring system features information on water quality from hydroponic plants and the ability to record farming activities from planting preparation to web-based harvesting. The test results of smart greenhouse monitoring system can display the hydroponic plant conditions and able to do the humidification control with an upper limit of 35 degrees celsius because plant can survive with disease under 35 degrees celsius, with small average offset for the sensor, and an average offset of 1.49 from TDS sensors, with temperature of 0.50 and pH of 0.34.

Greenhouse Monitoring System Using Wireless Sensor Networks (WSN) Based on IoT

“…The results showed that the proposed system could remotely monitor the environmental conditions inside a greenhouse via the MQTT protocol. A. Supriyanto et al [12] proposed an intelligent monitoring system for hydroponics systems. In this system, the DHT11 sensor was used to collect humidity values, and the DS18b20 sensor was utilized to detect water temperature.…”

LoraWAN-based intelligent multi-greenhouse monitoring and control

“…The goal was to manage and regulate these variables to improve conditions for optimal plant growth and yield. Arif Supriyanto and Fathurrahmani [6] proposed a research plan to develop a prototype for a greenhouse designed specifically for cultivation. The hardware of this greenhouse incorporates components such as the Arduino microcontroller, DHT11 sensor, pH sensor, TDS sensor, DS18b20 temperature sensor, ultrasonic sensor, and esp8266 WiFi module.…”

Smart Greenhouse Technology for Hydroponic Farming: Is it Viable and Profitable Business?

“…However, creating innovative ecosystems and instilling innovation orientation among hydroponic farmers is difficult. This issue needs to be addressed immediately so that technologies such as those mentioned previously, in addition to monitoring technology and mobile applications, can assist farmers in determining when, where, how, or what to plant in precision farming [24]. Developing low-cost hydroponic technologies is essential to reduce dependence on human labor, lower overall start-up and operational costs, and promote the profitability of hydroponic farming [25] As shown in Figure 6, conventional leaf vegetable farming costs less than SGH-or SSGH-based hydroponic systems.…”
