Smart Cultivation: In-Depth Analysis of NiuBoL Greenhouse Intelligent Environmental Monitoring Solution

In the wave of transformation from traditional agriculture to modern agriculture, greenhouses, as core facilities ensuring year-round supply of agricultural products, are experiencing a profound shift in management mode from “experience-driven” to “data-driven.” Traditional manual measurement and control methods are not only inefficient but also difficult to achieve precise and timely environmental parameter regulation.

Based on this, NiuBoL utilizes IoT technology to build a greenhouse environmental monitoring solution integrating environmental monitoring, data analysis, and precise regulation. By real-time capturing core environmental factors, this solution can significantly improve agricultural product quality, achieving refined, efficient, and modernized production.

Driving Core: Definition and Working Principle of Greenhouse Monitoring System

A greenhouse environmental monitoring system is an intelligent management platform integrating sensor technology, automation control technology, and wireless communication technology.

Its core logic follows the closed loop of “perception-transmission-decision-execution”:

• Perception: Sensor terminals real-time acquire physical parameters such as air, soil, and light.

• Transmission: Uploaded to the cloud via collectors through RS-485 or LoRaWAN wireless protocols.

• Decision: Cloud platform compares thresholds based on crop growth models to analyze if current environment is in optimal range.

• Execution: Automatically triggers control commands to link ventilation, shading, irrigation, and other actuators for physical regulation.

Precise Perception: Core Sensor Technical Specifications and Function Analysis

In greenhouses, sensor precision and stability directly determine planting quality.

Atmospheric Environment and Light Monitoring Series

1. Atmospheric Temperature Humidity Pressure Sensor (NBL-W-LBTH)

Role and Function: As the greenhouse “thermometer,” it real-time monitors basic meteorological elements inside the greenhouse. Temperature affects metabolism, humidity relates to transpiration and pest risk, while pressure monitoring provides reference for complex microclimate analysis. Mainly used to link skylights, fans, and wet curtains to maintain stable greenhouse climate.

2. Carbon Dioxide Sensor (NBL-W-CO2)

Role and Function: Monitors “carbon source” concentration in the greenhouse. In sealed greenhouses, photosynthesis often causes sharp CO2 drops. This sensor timely triggers ventilation or artificial CO2 supplementation, ensuring plants in efficient growth state, significantly improving yield.

3. Illuminance Sensor (NBL-W-LUX)

Role and Function: Simulates plant perception of brightness. By monitoring total illuminance, the system automatically determines whether to open shading nets to prevent burns or start supplementary lights on rainy days, ensuring crops get sufficient daily photosynthesis time.

4. Photosynthetically Active Radiation Sensor (NBL-W-PARS)

Role and Function: Specifically measures 400-700nm band energy essential for plant photosynthesis. It more scientifically reflects plants' true “production potential” than ordinary illuminance meters, often used in crop growth scientific analysis and precise supplementary lighting for high-quality flowers.

Soil Environment Monitoring Series

5. Soil Temperature Humidity Conductivity Sensor (NBL-S-TMC)

Role and Function: Directly feedbacks root survival environment. Humidity data used for automatic drip irrigation activation, conductivity (EC) reflects soil fertility and salt status. By monitoring EC value, precise water-fertilizer integration schemes can be achieved, preventing “seedling burn” or soil compaction from excessive fertilization.

6. Soil pH Sensor (NBL-S-PH)

Role and Function: Soil pH value determines effective nutrient absorption. This sensor real-time tracks acid-base dynamics, guiding farmers in scientific acid or alkali adjustment, solving lag pain points of traditional sampling assays.
