Policy Background for LoRa in Smart Agriculture:

According to the "Guidance on Vigorously Developing Smart Agriculture" issued by the Ministry of Agriculture and Rural Affairs (Document No. 3 of 2024), "Smart agriculture is an important focus for the development of modern agriculture and a strategic high ground for building a strong agricultural nation."

"By 2030, significant progress will be made in the development of smart agriculture, with major breakthroughs in key core technologies, the basic establishment of standards and testing systems, and the widespread application of advanced, reliable, domestically-produced technical equipment. The promotion and application in key regions, important fields, and critical links will make major breakthroughs, improving land productivity, labor productivity, and resource utilization efficiency. The level of digital and intelligent industry management services will significantly increase, and the informatization rate of agricultural production will reach approximately 35%. Looking forward to 2035, smart agriculture will make decisive progress, with full breakthroughs in key core technologies and the international advancement of technical equipment, realizing digital transformation across the entire agricultural industry chain. The informatization rate of agricultural production will exceed 40%, providing strong information support for building a strong agricultural nation."

  4. Improving Agricultural Management and Production Efficiency Through Smart Supervision, Enhancing Economic Benefits

LoRa-based Agricultural Greenhouse Remote Monitoring Solution:

The smart remote monitoring system for agricultural greenhouses can accurately collect parameters such as temperature, humidity, light intensity, and carbon dioxide concentration. In case of necessity, manual intervention can be carried out, adapting to the needs of different crops, reducing the likelihood of pests and diseases, and ultimately boosting economic returns.

The system mainly consists of the following components:

  1. Sample Collection System: This system is composed of low-power sensors that actively wake up to collect accurate data on temperature, humidity, and other environmental parameters at set intervals. When idle, the system enters a low-power sleep mode to reduce standby power consumption, thereby lowering maintenance costs.

  2. Data Transmission System: This system includes IoT transmission units. The LoRa nodes feature low power consumption, long-range capabilities, and strong anti-interference ability, providing a reliable medium for data transmission. LoRa gateways collect and aggregate data from multiple nodes and then transmit the data over long distances to the central processing system through communication methods like WiFi, 4G, or Ethernet.

  3. Central Control Processing System: This system integrates the collected data and controls the entire system through programmatic automation. With its remote transmission capability, the system can operate unattended, allowing for automated operation.

  4. Human-Machine Interaction System: This system displays the collected data in a graphical form from the central control system. The data is presented to the monitoring personnel via displays and allows for flexible editing of the interface.

  5. Automated Control System: This system includes actuators such as pumps and curtain machines, which can implement manual intervention in extreme conditions, such as timed irrigation or pest control.

Each system works collaboratively to provide an ideal growing environment for crops, and through automated operations, it reduces labor intensity, improves equipment utilization, and lowers both labor and maintenance costs.

Value of LoRa-based Remote Monitoring Solution:

As a leading wireless communication technology for IoT, LoRa provides the following advantages for the remote monitoring solution of agricultural greenhouses:

  1. Ease of Operation: Each system operates independently, with well-developed software functionality, a modular and graphical interface, making it easy to use.

  2. Practicality: Due to the widespread distribution of agricultural land, 4G and 5G mobile communication technologies with wide coverage are used in remote areas to ensure stable data transmission.

  3. Ease of Maintenance: Remote control commands can be issued directly through the central control system, including remote parameter settings and troubleshooting.

  4. Stability: The system is designed with industrial-grade components, ensuring reliable and stable operation.

This LoRa-based solution helps transform agricultural practices by providing efficient, reliable, and scalable monitoring of greenhouse environments, contributing to the development of modern and intelligent agriculture.
