Automatic Weather Station in Agricultural Microclimate Monitoring: Engineering Applications

In modern agricultural engineering projects, crop microclimate monitoring has become a core component for ensuring production stability and disaster prevention. Microclimate refers to environmental elements near the crop canopy, including air temperature, relative humidity, photosynthetically active radiation, wind speed and direction, rainfall, etc. These parameters directly affect crop physiological processes and the probability of disaster occurrence. The NiuBoL compact automatic weather station (field microclimate observer), as a modular industrial-grade device, supports multi-sensor integration, wireless data transmission, and cloud analysis, helping system integrators, IoT solution providers, and project contractors achieve real-time environmental perception and automated early warning.

The system emphasizes high-automation acquisition, long-distance transmission, and protocol compatibility, suitable for distributed farmland, orchards, and facility agriculture projects. Through precise data support for frost warning, irrigation optimization, and pest & disease risk assessment, engineering teams can significantly reduce meteorological disaster losses and improve overall project ROI.

Product Overview and Core Functions of Automatic Weather Station

The NiuBoL compact automatic weather station integrates a high-precision sensor array, data acquisition terminal, protective enclosure, and communication module, supporting on-site installation and long-term unattended operation. The system adopts a low-power design combined with solar/mains dual power supply to ensure continuity in remote agricultural areas. Data is uploaded to the cloud platform wirelessly (4G/LoRa optional), supporting multi-terminal access and API integration.

Core functions of the automatic weather station include:

• Multi-element real-time acquisition: air temperature, humidity, atmospheric pressure, wind speed, wind direction, rainfall, light intensity, etc.

• Automatic data processing: threshold judgment, trend analysis, alarm push

• Wireless transmission and storage: supports Modbus RTU/TCP, MQTT protocols, facilitating edge-cloud collaboration

• Expansion interfaces: reserved RS485, analog input, supports adding soil temperature/humidity or CO₂ sensors

This station is particularly suitable for scenarios requiring high timeliness monitoring, such as frost-sensitive crop areas, helping engineering companies build reliable agricultural IoT architecture from the perception layer.

The NiuBoL system integrates various professional meteorological sensors, each designed with emphasis on accuracy, durability, and interchangeability. The following table summarizes the main sensor technical parameters and application characteristics:

These sensors support interchangeable interfaces and automatic identification of access type, ensuring flexible system configuration. In engineering projects, temperature + humidity + wind direction combinations can be prioritized based on crop-sensitive elements (e.g., apples are highly sensitive to low-temperature thresholds).

System Integration Solutions and Compatibility of Automatic Weather Station

The design of the NiuBoL compact automatic weather station focuses on engineering-grade integration, supporting mainstream industrial protocols and architectures:

• Communication protocols: standard RS485 Modbus RTU/TCP for easy access to PLC or industrial gateways; optional MQTT over TLS, supporting cloud platforms such as Alibaba Cloud IoT, akenza, Thinger.

• Network options: 4G LTE backhaul (for wide-area coverage), LoRaWAN (low-power long-distance, suitable for ten-thousand-mu orchards), Ethernet (fixed sites).

• Edge integration: reserved interfaces for linking actuators (e.g., frost protection fans, sprinkler pumps) to achieve local closed-loop control and reduce cloud latency.

• Power and protection: IP65/IP67 enclosure, -40~85℃ operating range, solar power configuration supports remote deployment.

In project architecture, the station often serves as a perception-layer node, combined with edge gateways to form star or mesh topology, ensuring reliable data upload. System integrators can leverage its modular features for quick expansion to multi-site networks, supporting OTA firmware upgrades and remote diagnostics.

Application Scenarios of Agricultural Automatic Weather Station

The NiuBoL compact automatic weather station is suitable for various smart agriculture engineering scenarios:

• Orchard frost protection: deciduous fruit tree areas such as apples and pears, monitoring canopy temperature and radiation cooling conditions, supporting low-temperature warning models and linkage with fans/sprinklers.

• Facility agriculture microclimate regulation: greenhouse/hoop house projects, real-time tracking of temperature, humidity, and light for automatic ventilation, shading, and supplemental lighting control.

• Field crop environment monitoring: corn, rice, etc., combined with rainfall and wind speed data for drought/flood warning and pest & disease occurrence prediction.

• Research and demonstration bases: long-term fixed observation, providing high-resolution datasets to support crop model validation and climate adaptation research.

• Specialty planting areas: flowers, tea, Chinese medicinal herbs, etc., finely monitoring microclimate change patterns to optimize cultivation plans.

• Disaster prevention and mitigation systems: regional deployment to form meteorological disaster monitoring networks, supporting risk assessment by government or insurance institutions.

These scenarios highlight the equipment’s durability and data accuracy, helping project contractors meet the technical requirements of high-quality agricultural development.

Selection and Deployment Guide for Agricultural Weather Station

When selecting for engineering, consider the following factors:

1. Monitoring element combination: frost-sensitive crops prioritize temperature + humidity + wind direction; photosynthesis research requires adding PAR.

2. Site density and coverage: large orchards suggest 1 station per 50–100 mu; multi-point deployment improves spatial resolution.

3. Communication and power: remote areas prioritize LoRa + solar; grid-accessible areas optional 4G + mains.

4. Maintenance strategy: modular sensors facilitate on-site replacement; combined with cloud platform remote monitoring to reduce O&M costs.

Through these guidelines, system integrators can optimize configurations to match project budget and performance needs.
