The role of agricultural Internet of Things in modern agriculture

Smart agriculture refers to the use of IoT solutions when using agricultural practices. So, what do we mean by the agricultural Internet of Things? The IoT refers to the Internet of Things. It uses agricultural smart sensors to conveniently collect machine and environmental indicators.

At present, the use of new agricultural methods for plant cultivation is very popular among growers. However, the agricultural Internet of Things is one of the means of modern agriculture and is widely used worldwide.

In the intelligent agricultural control system, agricultural IoT sensors are needed to monitor agricultural parameters. Including temperature, humidity, light intensity, water nutrient solution content, pH value and EC value, CO, etc.

What is an agricultural IoT sensor?

Temperature sensor

Temperature is one of the key factors that determine the growth and development of plants. The temperature sensor measures real-time temperature readings through electrical signals.

The sensor collects data about temperature from a specific source. And convert the data into a form that the device or observer can understand. The temperature sensor accurately measures the slower temperature changes in critical applications such as facilities or rooms and sends them to the user platform.

Illumination sensor

All plants and flowers need a lot of sunlight. Each plant group has different responses and different physiological treatment light intensity. The illuminance sensor can be used to automatically control the lights, such as on/off. Farmers can monitor the light intensity without any human interference.

Soil pH sensor

Soil pH is a measure of soil alkalinity or acidity. The measuring range of soil pH is 1-14, where 7 is the neutral mark. The ideal range for most plants is between 6-7. Most plants prefer a neutral pH, from 6.2 to 7.0. However, many plants have special pH requirements, such as blueberries and pears, which are like very acidic soils, while cloves and clematis prefer more alkaline soils.

Even some, such as hydrangeas, change the color of the flowers according to the pH of the soil. The pH value of the soil where different plants are located is different. Therefore, we need to monitor the soil through soil pH sensors to ensure that the plants are in a suitable pH environment.

The applicability of the Internet of Things in agriculture

Smart agriculture is a system of high-tech, high-efficiency agriculture and sustainable food planting. It is an application that combines networked devices and innovative agricultural technologies. Smart agriculture mainly relies on the Internet of Things, which eliminates the manual labor of farmers and growers, thereby increasing productivity in various possible ways.

With the recent trend that agriculture is dominated by agriculture, the Internet of Things has brought huge benefits such as efficient water use and optimized investment. It has brought huge benefits, and in recent days, it has become a revolutionary agriculture.

Smart agriculture based on the Internet of Things improves the entire agricultural system through real-time monitoring of the agricultural environment.

With the help of sensors and interconnection, the agricultural Internet of Things can not only save farmers’ time, but also reduce the excessive use of water, electricity and other resources. It checks various factors such as humidity, temperature and soil, and provides clear real-time observations.

Advantages of Agricultural Internet of Things in Agricultural Development

For a long time, sensors have been introduced into agricultural operations. However, the problem with using traditional sensor technology is that we cannot obtain real-time data from the sensor. With the introduction of the agricultural Internet of Things, more advanced sensors are being used.

Agricultural sensors are now connected to the cloud via a wireless network. This allows us to understand real-time data from agricultural sensors and make decisions effective

The application of the Internet of Things in agriculture helps farmers monitor soil moisture in real time and achieve precise irrigation. The advancement of agricultural Internet of Things technology in agricultural operations enables agricultural Internet of Things sensors to be applied to every aspect of the farming process, such as how much time and resources it takes for seeds to become fully planted vegetables.

The agricultural Internet of Things is the second wave of green revolution. The benefits that farmers gain by adapting to the Internet of Things are twofold. It uses accurate data to improve farmers’ decision-making, helping farmers to increase production while reducing costs.

Application of Agricultural Internet of Things in Agriculture

Precision agriculture

Precision agriculture is one of the most famous applications of the Internet of Things in agriculture. Through the realization of intelligent agricultural applications such as livestock monitoring, agricultural environment monitoring, and weather monitoring, the breeding practice is more precise and controllable.

The goal of precision agriculture is to analyze the data generated by sensors in order to respond accordingly. Precision agriculture helps farmers generate data with the help of sensors and analyze the information to make smart and fast decisions. There are many complex farming techniques, such as irrigation management, livestock management, etc., which play a vital role in improving efficiency and effectiveness.

With the help of precision agriculture, you can analyze soil conditions and other related parameters to improve operational efficiency. Not only that, you can also detect the real-time working status of connected devices, and detect water and nutrient levels.

Smart greenhouse

In order to make our greenhouses more intelligent, the Internet of Things enables weather stations to automatically adjust climate conditions according to specific instructions. These sensors collect and transmit real-time data, which helps to accurately monitor the status of the greenhouse in real time.

With the help of sensors, the status of the greenhouse can be monitored via email or SMS alerts. Automatic and smart irrigation with the help of the Internet of Things. These sensors help provide information about pressure, humidity, temperature, and light levels.

Climate conditions

Climate plays a very important role in agriculture. An improper understanding of the climate has severely affected the quantity and quality of crop production. But IoT solutions enable you to understand real-time weather conditions. Weather station sensors are placed inside and outside the farmland. They collect data from the environment and use them to select crops suitable for growth and maintenance under specific climatic conditions.

The entire IoT ecosystem is composed of sensors that can more accurately detect real-time weather conditions such as humidity, rainfall, and temperature. The sensors used to detect all these parameters can be configured accordingly to meet the requirements of smart agriculture.

These agricultural IoT sensors monitor the condition of crops and the surrounding weather. If you find any disturbing weather conditions,

Crop management

Another important precision agriculture element is crop management equipment. They can be placed on the entire site like a weather station. Once established, they can collect data specifically needed for crop cultivation.

It is effectively used to collect all key data such as temperature, leaf water precipitation and overall crop health. Therefore, it becomes convenient to monitor crop growth and spot any abnormalities that might damage yield in any way: if caught early, it can be prevented.

Agricultural drone

One of the most promising advancements in agricultural technology is the introduction of agricultural drones into smart agriculture. These drones are also called unmanned air vehicles. Some people even think that these drones are more suitable for collecting agricultural data than satellites or airplanes.

They not only master the monitoring ability, but also perform various tasks instead of manual work. These tasks include prevention of infections and pests, planting crops, crop monitoring, agricultural spraying, etc.


It can be seen that with the advancement of science and technology, the advantages of the Internet of Things, such as cost-saving, rapid response, and remote monitoring, have been continuously integrated into modern agriculture. Whether it is planting or animal husbandry, the Internet of Things is indispensable. Modern agriculture led by the Internet of Things will gradually become the mainstream of agriculture.
