INTRODUCTION Aeroponics is an innovative technique used in both research and commercial crop production, where plant roots are suspended in the air and periodically sprayed with a nutrient solution. This method offers numerous advantages over traditional agriculture, including reduced water and nutrient consumption, enhanced growth rate, increased plant density, and improved irrigation system quality. It is crucial to continuously monitor the consumption and level of the nutrient solution, as well as ensure the proper functioning of pumps. Failure to do so could lead to crop loss due to insufficient nutrient supply. Therefore, effective data transmission is of utmost importance in the monitoring and control of aeroponic growing chambers. This paper presents an alternative approach that utilizes sensors and Wi-Fi technology for monitoring and controlling aeroponic systems. By implementing this method, it becomes easier to remotely monitor and manage aeroponic systems from any location, reducing the risk of crop failure and ensuring optimal plant growth. 2. Research Methodology The base control unit microcontroller chosen for this aeroponic system is the Node MCU. This microcontroller offers efficient interfacing capabilities with the sensing devices and supports Wi-Fi connectivity for seamless data collection and transmission to the ThingSpeak portal. The setup of the aeroponic greenhouse box includes a pump that is connected to the box, supplying water spray through pipes inside. This arrangement ensures the adequate delivery of water and nutrients to the suspended plant roots. Two types of sensors are utilized in this system. The first is the DS18B20 temperature sensor, which is water-resistant and measures the ambient temperature in the surrounding environment. This data provides crucial information about the temperature conditions within the aeroponic setup. The second sensor employed is the LDR (Light Dependent Resistor) sensor, which measures the intensity of light in lux. This sensor enables monitoring the amount of light received by the plants, which is crucial for their growth and development. The Node MCU microcontroller gathers the data from both the temperature sensor and the LDR sensor. It then transfers these data points to the ThingSpeak portal through its Wi-Fi capabilities. This allows for centralized storage and monitoring of the collected data, providing valuable insights for analysis and control of the aeroponic system. 3. Components/ Software Used 3.1 ESP8266 The ESP8266 is an affordable Wi-Fi chip developed by Espressif Systems. It can be used as a standalone device or as a UART to Wi-Fi adaptor, enabling other microcontrollers to connect to Wi-Fi networks. For instance, it can be connected to an Arduino board, adding Wi-Fi capabilities to the Arduino. Its practical application is often as a standalone device. With the ESP8266, you can control inputs and outputs similar to an Arduino, but with added Wi-Fi capabilities. This feature allows projects to be brought online, making it ideal for home automation and Internet of Things (IoT) applications. The ESP8266 has gained popularity due to several key factors: 1. Low-cost: ESP8266 boards are available at a starting price of $3 or even less, depending on the specific model. 2. Low-power: The ESP8266 consumes minimal power compared to other microcontrollers and can enter deep sleep mode to further reduce power consumption.
