What is Greenhouse Monitoring System?

Greenhouse monitoring system: the green guardian of intelligent agriculture

With the rapid development of agricultural technology, modern greenhouses play an increasingly important role in agricultural production. Greenhouses can not only regulate the adverse effects of external climate change, but also provide the right environmental conditions to promote the healthy growth of crops, improve yield and quality. In order to more accurately regulate the internal environment of greenhouses, greenhouse monitoring systems have emerged as an important part of modern intelligent agriculture.

 I. Overview of greenhouse monitoring system

The greenhouse monitoring system is a comprehensive solution that integrates sensor technology, Internet of Things (IoT), big data analysis and intelligent control algorithms. The system monitors environmental changes in the greenhouse, such as temperature, humidity, light intensity, carbon dioxide concentration and other key parameters in real time by deploying a variety of high-precision sensors in the greenhouse. The monitored data is transmitted to a cloud platform or local server via the Internet of Things. After processing and analyzing, the system is able to automatically adjust the equipment in the greenhouse, such as the temperature control system, humidity control system, irrigation system, etc., in order to ensure that the crops grow in an optimal environment.

At the heart of the system is a network of sensors throughout the greenhouse that act as “senses” of the environment, constantly collecting key data. These data are transmitted to the cloud or local servers in real time through the Internet of Things (IoT) technology, and after big data analysis, the system adjusts the temperature control, irrigation, ventilation and other equipment automatically or according to the preset rules to realize the intelligent regulation of the environment.

 Second, greenhouse greenhouse monitoring system required sensors and their role and value

In order to achieve accurate monitoring of the greenhouse environment, greenhouse monitoring systems usually need to use a variety of sensors to collect data in real time. The following are the common sensors and their roles and values:

1. Temperature Sensors

   - Role: Used to monitor the air and soil temperature inside the greenhouse. Temperature is one of the most important factors affecting the growth of plants. Excessively high or low temperatures can adversely affect crops.

   - Value: By monitoring the temperature, the system can automatically adjust the heating or cooling equipment in the greenhouse to ensure that the crops grow within the appropriate temperature range, thus improving yield and quality.

2. Humidity Sensor

   - Function: It is used to monitor the air and soil humidity in the greenhouse. Humidity has an important effect on crop transpiration, photosynthesis and the occurrence of pests and diseases.

   - Value: By monitoring humidity, the system can automatically adjust the humidifying or dehumidifying equipment in the greenhouse to maintain a suitable humidity environment, which is conducive to the healthy growth of crops and reduce the occurrence of pests and diseases.

3. Light intensity sensor

   - Role: Used to monitor the light intensity in the greenhouse. Light is the key factor for crop photosynthesis, and suitable light intensity is crucial for plant growth.

   - Value: By monitoring the light intensity, the system can automatically adjust the greenhouse shading equipment or supplemental light equipment to ensure that the crops get sufficient and suitable light to promote their normal growth.

4. Carbon Dioxide Concentration Sensor（CO2 sensor）

   - Role: Used to monitor the carbon dioxide concentration in the greenhouse. Carbon dioxide is an important raw material for crop photosynthesis, and its concentration directly affects the efficiency of photosynthesis and growth rate of crops.

   - Value: By monitoring the carbon dioxide concentration, the system can automatically adjust the ventilation equipment or carbon dioxide supplementation equipment in the greenhouse to maintain a suitable carbon dioxide concentration environment and improve the photosynthetic efficiency and growth rate of crops.

5. Soil Moisture Sensor

   - Role: Used to monitor the moisture content in the soil in real time to help the system understand the degree of wetness of the soil.

   - Value: When the soil moisture is too low, the system can automatically turn on the irrigation equipment to replenish the water in the soil to avoid crops growing poorly due to lack of water.

6. Soil pH Sensor

   - Function: Used to monitor the acidity and alkalinity (pH) of the soil in real time. Different crops have different needs for soil pH, too high or too low pH will affect the nutrient absorption of plants.

   - Value: The system can automatically adjust the pH value of the soil according to the monitoring results to ensure that crops can grow in the most suitable soil environment.

7. Soil Nutrition Sensor (Optional)

   - Function: Used to monitor the nutrients in the soil, such as nitrogen, phosphorus and potassium.

   - Value: To guide precise fertilization, to ensure that crops get sufficient nutrients, and to avoid the waste of resources and environmental pollution caused by excessive fertilization.

 III. Advantages and application value of greenhouse monitoring system

1. Improve production efficiency

   - Through real-time monitoring and intelligent regulation, the greenhouse monitoring system can provide a stable and suitable growing environment without increasing resource consumption, thus greatly improving the productivity of crops.

Through automated management, farmers no longer need manual intervention, thus reducing labor costs and being able to avoid unnecessary waste of resources.

3. Realization of remote monitoring and management

   - Modern greenhouse monitoring systems are usually equipped with remote monitoring functions, users can view the real-time data and environmental conditions inside the greenhouse anytime, anywhere through smart phones or computers. This remote management function greatly improves the convenience of greenhouse management, farmers do not have to frequently enter the greenhouse for inspection and adjustment, reducing labor intensity, while improving management efficiency.

4. Improve crop quality

   - Precise environmental control can not only increase crop yields, but also improve crop quality. Through the greenhouse monitoring system, the environmental parameters can be customized and regulated according to the needs of different crops, so as to make the crops grow in the most suitable conditions, and ultimately achieve high quality and high yield.

5. Real-time monitoring and early warning

   - Greenhouse monitoring system can real-time monitoring of environmental parameters in the greenhouse, and in abnormal situations in a timely manner to issue early warnings, providing farmers with a valuable window of time for emergency treatment. For example, when the temperature is too high or humidity is too low, the system will automatically alarm to remind farmers to take measures to avoid crop damage.

6. Intelligent regulation and energy saving

   - The system can automatically regulate greenhouse equipment according to monitoring data to provide a suitable growing environment for crops, while realizing energy saving and reducing production costs. For example, through intelligent control of the irrigation system to avoid overwatering and reduce the waste of water resources; through the optimization of the ventilation system to reduce energy consumption.
