IoT sensors in agriculture

In agriculture, IoT based sensors mainly include the following:

Air temperature and humidity sensors: used to monitor the temperature and humidity of the air to help farmers understand the air conditions in the environment where crops are grown.

Soil temperature and humidity sensors: used to monitor the temperature and humidity of the soil, helping farmers to understand the condition of the soil so that they can choose the right crop cultivation and management measures.

PH Sensor: Used to monitor the PH value of the soil, helping farmers to understand the acidity and alkalinity of the soil, so as to choose the appropriate crop planting.

Illuminance Sensor: Used to monitor the light intensity of the environment to help farmers understand the light condition of the growing environment of the crops, so as to adjust the environmental conditions in the greenhouse or greenhouse.

CO2 Concentration Sensor: Used to monitor the carbon dioxide concentration in the environment, to help farmers understand the carbon dioxide status of the growing environment of crops, so as to adjust the environmental conditions in the greenhouse or greenhouse.

Wind Speed and Direction Sensor: Used to monitor the wind speed and direction of the environment, helping farmers to understand the weather conditions, so as to take appropriate management measures.

Rainfall Sensor: Used to monitor the rainfall of the environment, helping farmers to understand the weather conditions, so as to take appropriate management measures.

Pest and Disease Sensors: Used to monitor crop pest and disease conditions, helping farmers to detect pest and disease problems in a timely manner, so as to take appropriate management measures.

These sensors can monitor the growing environment and growth conditions of crops in real time, helping farmers to understand the situation of crops in a timely manner and take appropriate management measures to improve the efficiency of agricultural production and management level.

IoT sensors in agriculture have the following features and advantages:

Real-time monitoring: IoT sensors are able to monitor various parameters in the growing environment of crops in real time, such as temperature, humidity, light, carbon dioxide concentration, etc., as well as the growing conditions of crops, such as biomass, pests and diseases.

Accurate data: IoT sensors can provide accurate data monitoring and analyses, helping farmers to more accurately understand the crop growing environment and growth conditions, so as to take more scientific and rational management measures.

Improve efficiency: IoT sensors can automate the monitoring and management of the agricultural production process, improve production efficiency and management level, and reduce manual intervention and labour intensity.

Optimise resource allocation: IoT sensors are able to monitor various data during crop growth, helping farmers to control the amount of resources used more accurately, avoid waste and pollution, and optimise resource allocation.

Improve the quality of agricultural products: Through the accurate monitoring and management of crop growth environment and growth conditions by IoT sensors, the quality of agricultural products, such as taste and nutritional value, can be improved.

Adapt to the future development of intelligent agriculture: IoT sensors, as the key technology of the perception layer in the information age, can adapt to the future development needs of intelligent agriculture and provide more accurate and reliable data support and intelligent management solutions for intelligent agriculture.

Remote monitoring and management: IoT sensors can be used to achieve remote monitoring and management through the Internet or mobile networks, so that farmers can learn about the growing environment and growth conditions of their crops at any time and any place, so that they can take appropriate management measures.

Intelligent decision support: IoT sensors can be used in conjunction with intelligent decision support systems to provide farmers with more intelligent and precise decision support, such as planting plans, fertiliser recommendations, pest and disease warnings, etc., through the analysis and processing of monitoring data.

Agricultural sustainable development: IOT sensors can help farmers manage and utilise agricultural resources more scientifically and rationally, improve the efficiency of resource utilisation, reduce environmental pollution and damage, and promote the sustainable development of agriculture.

Agricultural safety traceability: IOT sensors can monitor the growing environment and growth conditions of crops, record the production process and quality and safety information of agricultural products, help establish a quality and safety traceability system for agricultural products, and guarantee food safety.

Price and cost of agricultural IoT sensors:

IoT sensors in agriculture, the cost and price of IoT-based sensor devices depend on different factors, such as type, quality, and quantity. Generally, the cost of IoT sensors ranges from $10 to hundreds of dollars dollars depending on factors such as the type, functionality, accuracy, and quality of the sensor.

For some IoT sensors in agriculture, such as soil moisture sensors, temperature sensors, etc., the general price ranges from $30 to several $100 dollars. For some more advanced sensors, such as carbon dioxide sensors and light sensors, the price may be higher.

In addition to the price of the sensor itself, the cost of other related equipment, such as data collectors, data transmission equipment, data processing and analysis software, etc., also needs to be considered. The cost of these devices also needs to be assessed on a case-by-case basis.

Overall, the cost of IoT sensors and other related equipment needs to be evaluated and selected based on specific application scenarios and needs. In some cases, basic IoT applications can be realised through the use of low-cost sensors and other devices, while in other cases, more sophisticated IoT applications may need to be realised using more advanced devices.

Communication methods for agricultural IoT sensors:

The two main communication methods for IoT sensors in agriculture are wireless and wired communication methods. Wireless communication methods mainly include LORA, WIFI, 4G, 5G, etc., which have the advantages of no wiring, convenience and flexibility, but the transmission rate is slower and the anti-interference ability is weaker. The wired communication method includes wire carrier or carrier frequency, coaxial line, switching signal line, RS232 serial port, RS485, USB, etc., which has the advantages of fast transmission rate, high stability, etc., but the wiring is troublesome and easy to damage. In the application of agricultural Internet of Things, the choice of sensor communication method should be evaluated and selected according to the specific application scenarios and needs, taking into account the communication distance, transmission rate, stability, cost and other factors.

In summary, IoT sensors in agriculture have a variety of features and advantages, which can achieve real-time monitoring of the crop growth environment and growth conditions, accurate data analysis, remote monitoring and management, intelligent decision-making support, improve production efficiency and management level, optimize resource allocation, improve the quality of agricultural products and safety traceability and other functions, providing strong support for the development of modern agriculture.
