Maintaining optimal conditions within fermenters is essential for maximizing microbial productivity and ensuring process efficiency. This lesson focuses on key parameters—temperature, foam, pH, carbon dioxide, oxygen, and pressure—and their precise measurement and control strategies in fermentation systems.Temperature ControlTemperature regulation is critical due to the exothermic nature of many fermentation processes. In small laboratory fermenters, temperature is commonly...

Key Elements for Plant Nutrition

24.8K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Control systems are everywhere in contemporary society, influencing diverse applications from aerospace to automated manufacturing. These systems can be found naturally within biological processes, such as blood sugar regulation and heart rate adjustment in response to stress, as well as in man-made systems like elevators and automated vehicles. A control system is essentially a network of subsystems and processes that collaboratively convert specific inputs into desired outputs.

  • Agricultural Technology
  • Wireless Sensor Networks
  • Hydroponics

Background:

  • Information and communication technology (ICT) in agriculture enables stable, high-quality crop production with reduced labor.
  • Wireless sensor networks (WSNs) in agricultural systems face challenges like packet transmission errors and equipment failure in harsh environments.
  • Existing systems often struggle with reliable data transmission in complex growing conditions.

Purpose of the Study:

  • To propose a reliable wireless control system for hydroponic tomato cultivation.
  • To address packet transmission errors and system failures in agricultural WSNs.
  • To achieve precise, real-time cultivation control with zero data loss.

Main Methods:

  • Utilized the 400 MHz wireless band, offering superior obstacle diffraction compared to the 2.4 GHz band.
  • Implemented the IEEE 802.15.6 standard, incorporating a guaranteed time-slot method for zero-data-loss communication.
  • Integrated fault tolerance and self-healing functions to ensure system resilience.

Main Results:

  • The 400 MHz band wireless communication demonstrated robustness, unaffected by plant growth.
  • Achieved a significantly lower packet error rate compared to the 2.4 GHz band.
  • Successfully implemented real-time hydroponic liquid supply control with no data loss.

Conclusions:

  • The proposed system provides a reliable solution for hydroponic cultivation using WSNs.
