Smart Greenhouse Monitoring and Controlling based on NodeMCU

Abstract

Food security is one of the major rising issues as the human population is larger and the land available for cultivation is smaller, as well unassured affairs happened often in society especially in the current CoVID-19 rapidly spread days. To mitigate this condition, further improve the yields and quality of food, this paper proposed a smart and low-cost greenhouse monitoring and control system, which mainly consists of sensors, actuators, LCD display and microcontrollers. DHT22 sensor is used to get the surrounding temperature and humidity in the greenhouse, and NodeMCU is used as the main microcontroller. Some other facilities such as fan and heater are used to adjust the inside environment. The system could monitor the growth environment continuously with Internet-connected, the monitoring data is transmitted and stored in the ThingSpeak cloud, the users can visualize the live data through a webpage or phone APP in real-time. If the environment condition is out of the predefined level, the environment is monitored continuously, and the system can be adjusted automatically. This system can be deployed in the greenhouse simply and maintain the greenhouse environment in a normal range dynamically and continuously.

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

“…The results of the system were promising, and the researchers concluded that it could be used in other greenhouses. Y. Liu [14] Proposed a smart greenhouse to monitor the ambient temperature and humidity of the greenhouse. A DHT22 sensor was used to collect both temperature and humidity, and an ESP8266 microcontroller was utilized to collect the sensor data, which was then transmitted and stored in the cloud database via a wireless network.…”

A Smart Remote Monitoring System for Prenatal Care in Rural Areas

“…ThingSpeak which is a cloud platform predominantly used to process the sensor data and visualizing the result out of sensory tDCS prototype. Using the same technologies, crop health can be maintained by ensuring greenhouse conditions with help of IoT sensors and processing the output over ThingSpeak platform [22].…”
