It supports real-time collection of multiple elements such as temperature, humidity, CO₂, light, and soil moisture. It is compatible with Modbus, MQTT, 4G/LoRaWAN protocols and can be linked with irrigation, ventilation, and shading systems. This article systematically explains the value of NiuBoL small weather station in greenhouse planting from an engineering application perspective, with a focus on integration solutions, system compatibility, and real project implementation cases, providing users with reliable decision-making references.

Core Value of Small Weather Station in Greenhouse Planting

In modern facility agriculture, greenhouses break seasonal limitations and achieve off-season, high-quality crop production by artificially regulating parameters such as temperature, humidity, carbon dioxide concentration, and light. However, minor fluctuations in environmental parameters often directly affect crop photosynthesis, transpiration, and the incidence of pests and diseases. As a dedicated environmental monitoring node, NiuBoL small weather station can collect key meteorological elements inside and outside the greenhouse in real time and continuously, providing a data foundation for precise regulation and helping large-scale greenhouses transform from "experience-based management" to "data-driven" management.

Compared with traditional manual inspection or single sensors, NiuBoL small weather station adopts a modular design, supports multi-element integration and expansion, and uploads data to cloud platforms or local SCADA systems through industrial-grade protocols. This significantly reduces manual duty costs and improves the response speed of environmental regulation. In actual projects, the system can help greenhouse operators control environmental deviations within ±0.5℃ (temperature) and ±3% RH (humidity), thereby stabilizing the crop growth cycle and reducing yield losses caused by high-temperature stress, low-temperature frost damage, or high-humidity induced diseases.

Working Principle and Technical Features of Greenhouse Weather Station System

NiuBoL small weather station is built based on high-precision industrial sensors and embedded data loggers. The core uses digital compensation algorithms to eliminate environmental interference. The temperature and humidity sensor combines platinum resistance and capacitive elements for fast response; the light sensor adopts photosynthetically active radiation (PAR) measurement mode to quantify the light energy available to crops; the optional CO₂ sensor monitors gas concentration changes through non-dispersive infrared (NDIR) principle; soil temperature and humidity and pH sensors are directly inserted into the root zone medium to provide moisture and pH data.

The system highlights "blind-spot-free monitoring" and "low-power design": sampling frequency is configurable from 1s to 60s, and built-in data caching ensures continued transmission after network disconnection. The communication module supports RS485, 4G, LoRa, and Ethernet interfaces, and is compatible with Modbus RTU/TCP and MQTT protocols by default, making it easy to connect with existing greenhouse controllers, PLCs, or IoT platforms. The power system uses solar panels + lithium battery backup to meet the needs of long-term deployment in off-grid or remote greenhouses. The protection rating is above IP65, adapting to high humidity, condensation, and dusty environments.

These technical features ensure the system maintains data stability and long-term reliability under greenhouse microclimate conditions, providing credible input for subsequent automated control.

System Composition and Integration Solutions of Weather Station

NiuBoL small weather station adopts a modular architecture, which is convenient for flexible configuration according to greenhouse size and crop type. It mainly includes the following parts:

Sensor Module
   Integrates sensors such as air temperature and humidity, CO₂ concentration, photosynthetically active radiation, soil temperature and humidity, and soil pH. It supports hot-swappable expansion and can access up to 12 channels of elements, covering the micro-environment inside the greenhouse and reference meteorology outside the greenhouse.

Data Acquisition and Transmission Unit
   The high-performance ARM data logger is responsible for synchronous acquisition and preprocessing of multiple signals and supports local SD card storage. The transmission unit provides multiple communication methods and can directly connect to the user's cloud platform or enterprise MES system to achieve bidirectional interaction between data and actuators.

Installation and Power System
   Standard bracket height is 1.5m~3m, suitable for fixed installation inside or at the side of the greenhouse. The power module includes high-efficiency solar panels and intelligent charging controllers, with a battery life of more than 7-10 days in continuous rainy weather.

Data Platform and Control Interface
   NiuBoL's self-developed platform or open API supports real-time curve display, historical data query, threshold alarms, and linkage control. Users can set upper and lower limits for temperature, humidity, and CO₂. Once the limits are exceeded, ventilation, irrigation, supplementary lighting, humidification, and other execution equipment can be triggered via SMS, APP, or API.

The system has strong compatibility and has successfully achieved seamless integration with a variety of mainstream greenhouse controllers (such as PID regulators, water and fertilizer integrated machines, and curtain motors), forming a closed loop of "monitoring-decision-execution" to meet the needs of large multi-span greenhouses or multi-zone independent control projects.

Project Application Cases

North China Vegetable Multi-Span Greenhouse Project
   In 2023, NiuBoL deployed 30 sets of small weather stations for a thousand-mu facility vegetable base in Hebei, forming an environmental monitoring grid inside the greenhouses. The system integrates CO₂ and light sensors and links with existing water and fertilizer integrated machines and ventilation systems. When the CO₂ concentration inside the greenhouse is lower than 400ppm, the air supply device is automatically activated; when humidity exceeds 75% RH, dehumidification fans and side windows are linked. After the project was put into operation, the incidence of tomato gray mold decreased by 65%, single-season yield increased by 18%, and irrigation water utilization efficiency improved by 22%. Data is uniformly connected to the base cloud platform, and managers can remotely monitor the environment of multiple greenhouses through mobile APP, achieving low-labor operation.

South China Flower Intelligent Greenhouse Project
   A high-end flower export base in Guangdong introduced NiuBoL small weather station and camera linkage solution. The weather station monitors temperature, humidity, light, and soil moisture in real time. Data is connected to the PLC controller to achieve automatic shading, supplementary lighting, and drip irrigation control. At the same time, the platform supports video overlay of environmental parameters for remote inspection and quality traceability. After project implementation, the finished rate of Phalaenopsis increased from 82% to 95%, and the rework rate caused by environmental fluctuations was greatly reduced, gaining recognition from export certification agencies.

Northeast Fruit and Vegetable Seedling Greenhouse Project
   To cope with spring low-temperature frost damage, a seedling center in Liaoning adopted NiuBoL indoor and outdoor combination solution. The outdoor station monitors wind speed, rainfall, and temperature outside the greenhouse, while the indoor station focuses on temperature, humidity, and CO₂ inside the greenhouse. The system pushes data to mobile phones via NB-IoT. When nighttime temperature approaches the critical value, the heating system is automatically started. After one seedling cycle, the seedling survival rate increased by 14%, providing uniform and robust seedlings for subsequent transplanting and significantly shortening the slow seedling period after field planting.

Northwest Facility Grape Planting Project
   A Gobi greenhouse grape base in Gansu deployed NiuBoL small weather station, focusing on integrating soil temperature and humidity and light sensors, linked with drip irrigation controllers. The system estimates precise water replenishment based on transpiration, avoiding root diseases caused by excessive moisture or affecting fruit expansion due to drought. Operation data shows that grape sugar content increased by 1.2°Brix and fruit cracking rate decreased by 70%, achieving dual improvement in water and fertilizer saving and quality.

These cases fully verify the engineering applicability and integration value of NiuBoL small weather station under different climatic zones and crop types.
