Sensors such as temperature and humidity, wind speed and direction, light intensity, and gas are usually used in smart agriculture to detect factors such as temperature and humidity, wind speed and direction that affect crop growth. Temperature and humidity sensor: The important equipment of the intelligent agricultural monitoring system is the temperature and humidity sensor, which is widely used in greenhouses. Light sensor The light sensor in the intelligent agricultural monitoring system is usually suitable for agricultural greenhouses and can be used to detect light intensity.

China has been a big agricultural country since ancient times. Agriculture is the lifeblood of the national economy. The development of agriculture is also related to social stability. Although my country's agricultural production labor force is sufficient, there is a relative shortage of professional and technical personnel, and many advanced agricultural new technologies cannot be applied in time in my country. This has led to a series of adverse effects such as unreasonable allocation of labor resources, unscientific production methods, waste of resources, and impact on output.

In order to better solve these problems, make full use of various resources, and further develop Chinese agriculture, all parts of the country have begun to vigorously develop intelligent agriculture. With the development of science and technology and the Internet of Things, smart agriculture makes the agricultural field more intelligent, scientific and convenient, which is of great help to the development of agriculture.

What is smart agriculture?

Sensor technology is the core technology of smart agriculture. |||As an advanced product of modern agricultural development, sensor technology can monitor the environmental elements required for crop growth under the macro-control of the Internet of Things and according to the planting characteristics of different agricultural products. Through this intelligent monitoring, various environmental elements can always be kept within the optimum range for crop growth, thereby further improving planting efficiency and yield.

What are the sensors commonly used in smart agriculture?

Sensors such as temperature and humidity, wind speed and direction, light intensity, and gas are usually used in smart agriculture to detect factors such as temperature and humidity, wind speed and direction that affect crop growth.

1. Temperature and humidity sensor: The important equipment of the intelligent agricultural monitoring system is the temperature and humidity sensor, which is widely used in greenhouses. Greenhouse managers who install temperature and humidity sensors can grasp the temperature and humidity values in the greenhouse in real time, and set the upper and lower limits of temperature and humidity according to the suitable growth environment for crops. When the temperature and humidity value in the greenhouse exceeds the limit, an alarm message can be issued in time to remind the management personnel to pay attention.

2. Wind speed and direction sensor: In the intelligent agricultural monitoring system, the wind speed and direction sensor is mainly used outdoors and can form a weather station. The function of shading and heat preservation in the greenhouse is mainly realized by shading net and roll film. If the wind speed is too high when placing the shade net or roll film, it will be damaged. The installation of the wind speed and direction sensor system will be calculated based on the return value detected by the sensor. When the wind speed is too high, the sunshade net and roll film can be retracted in time to avoid losses.

3. Light sensor The light sensor in the intelligent agricultural monitoring system is usually suitable for agricultural greenhouses and can be used to detect light intensity. Managers can clearly know whether the light is suitable for the growth of crops, so as to make corresponding adjustments.

4. Gas sensor: The carbon dioxide sensor in the intelligent agricultural monitoring system is mainly used in the greenhouse, which can monitor the carbon dioxide concentration in the environment in real time and upload the data to the cloud platform. The administrator can judge whether the shed needs ventilation according to the carbon dioxide concentration value, so as to ensure that the carbon dioxide value is always kept within the range suitable for the growth of crops, so as to ensure that the crops have a healthy growth environment and improve the yield and quality.

What problems still exist in smart agriculture?

In fact, China's smart agricultural sensor technology is still in its infancy and cannot fully meet the various needs of smart agricultural development. There are relatively few R&D personnel, which still hinders the further development of intelligence and automation in agriculture. In addition, smart agricultural sensors are also in their infancy, or can only initially monitor environmental factors. In the face of some force majeure harsh environment sensors, stability and practicability are still lacking.

Although smart agriculture has promoted the development of my country's agriculture, in this regard, the development of my country's smart agricultural sensors still has a long way to go.
