Temperature and humidity sensors and light intensity sensors are commonly used sensors in smart agriculture

What are the sensors commonly used in smart agriculture?

With the continuous development of modern society, traditional agricultural and animal husbandry production methods can no longer meet the needs of the development trend of human civilization, and modern agriculture is slowly being applied to the global manufacturing industry. Agricultural and animal husbandry sensors make traditional agriculture develop in the direction of intelligent systems, automation technology and modern agricultural remote operation. It is a kind of sensor widely used in modern agriculture at present. It is widely used in temperature and humidity monitoring in the whole process of vegetable greenhouses, soil layers, outdoor natural environment, green plant leaves, grain and fruit and vegetable storage.

Its purpose is to improve the efficiency of agriculture, innovate the agricultural business model, promote green manufacturing, and improve ecological environment protection.

Smart agriculture is the deep integration of the Internet of Things and traditional agriculture. Sensors can not only solve the limitations of natural factors such as temperature, but also complete remote control scientific research and detection in fields, greenhouses, aquatic products, livestock and other industries, and reasonably reduce the consumption of human resources. Scientific proof can also be used to improve the ability of all agriculture and animal husbandry to resist earthquake disasters and risks, and increase the output rate of agriculture and animal husbandry. Agricultural and animal husbandry sensors make traditional agriculture develop in the direction of intelligent systems, automation technology and modern agricultural remote operation.

Sensing technology has always been favored by many agricultural and animal husbandry workers. Several common sensors in modern agriculture are introduced in detail below.

1. Temperature and humidity sensor.

It is a kind of sensor widely used in modern agriculture at present. It is widely used in temperature and humidity monitoring in the whole process of vegetable greenhouses, soil layers, outdoor natural environment, green plant leaves, grain and fruit and vegetable storage. The wireless network temperature sensor is used to test the temperature and humidity of the gas in the natural environment of agriculture and animal husbandry. It is generally installed in the indoor ventilation and shade of vegetable greenhouses or animal houses. Soil temperature and humidity sensors are installed in the soil layer at the root of the crop. When installed, the sensor covers the deep soil according to the different rhizomes of the crops. Generally, 2-4 sensors are installed in each greenhouse or greenhouses of different lengths to test the ground temperature, water composition and changes in the whole process of crop growth and development, so as to facilitate timely and appropriate irrigation.

2. Light intensity sensor.

Illuminance refers to the lumen value obtained by the enterprise on the total surface area of the lighting fixture. In modern agriculture, light intensity sensors are widely used silicon blue solar detectors that are sensitive to dark light. They have the characteristics of easy installation, good moisture resistance, wide detection range, and long transmission distance. Especially in vegetable greenhouses suitable for agriculture and animal husbandry, it is used to test whether the light required for crop growth and development is the best state for crop growth and development, so as to decide whether to use soft light or shade.

3. Wind speed sensor.

Wind speed sensors are mainly used outdoors to establish climate and wind detection and collection applications. Sunscreens and rolls are widely used in greenhouses for shading and thermal insulation applications. If the wind is too strong, it will cause damage to the sunscreen and roll film. The system software will calculate and solve according to the wind information content sent by the wind, so that the sunscreen and roll film can be retrieved immediately in the case of strong winds, so as to prevent the sunscreen and roll film from being damaged by strong wind. membrane damage.

4. Carbon dioxide sensor.

Specified as a CO2 smart transmitter, the sensor uses a silicon-based non-transmissive infrared sensor with a unique built-in reference material; excellent single-light and double-light wavelength accurate measurement, no moving parts, and extraordinary long-term reliability. The sensor monitors the CO2 concentration value in the room in real time, and adjusts the CO2 vapor filling amount to ensure the CO2 concentration value required for the photosynthesis of the home plant.

5. Trace element sensor.

It can generally be used to detect the content of various trace elements in the culture solution prepared by soilless culture technology and natural environment, and can also be used to detect the content of trace elements in the soil layer of general greenhouses and greenhouses, so as to determine whether fertilization is required.

With the accelerated development of modern agriculture, the scope of application of agricultural and animal husbandry projects is expanding. In the future, various types of sensors will appear in agriculture and animal husbandry, which will bring a lot of convenience to our daily life. It is expected that the development of high and new technology can promote the rapid development trend of agricultural technology in my country, and enable farmers to enter the era of modern agriculture in an all-round way.
