With the advancement of science and technology, the productivity of all walks of life has been greatly improved, and the field of agriculture is of course no exception. For example, smart agriculture based on the Internet of Things can obtain a large amount of data through sensor technology, and quickly Make decisions that conform to the law of crop growth and promote the further improvement of crop yields.

Smart agriculture is an advanced stage of agricultural development. By using sensor technology, computer network and communication technology, automatic control technology, etc., various sensor equipment and data transmission equipment are arranged on the agricultural production site, so that the fields can be planted intelligently, visualized management, intelligent early warning, Intelligent decision-making, etc. are all realized. This article will introduce several commonly used sensor devices from the aspects of agricultural environment and seedling situation.

Monitoring of agricultural environmental parameters

There are many factors that affect the growth of crops, such as soil, climate, water, varieties, pests and weeds, etc. The yield of crops is the result of the combined influence of these factors. Therefore, in the field of modern agriculture, it is far from enough for agricultural workers to make decisions based on experience. It is necessary to rely on corresponding sensor technology to obtain as detailed environmental information as possible, and to rely on this information to make decisions.

In order to know the soil condition of farmland in real time, agricultural workers can choose to install corresponding agricultural sensors for data collection. Here we need to use agricultural sensors: soil moisture sensor, soil temperature sensor, soil PH value sensor and illuminance sensor and other equipment. After installing these devices, detailed soil environment data for each plot, as well as fertilizer, water, and possible future yields required for planting different crops can be obtained. Based on these data, the farm's production plan can be precisely arranged.

Smart agricultural sensors can realize all-weather uninterrupted monitoring, and remote monitoring equipment can automatically collect real-time soil environment data. Through accurate monitoring of the soil environment and rapid early warning of abnormal conditions, agricultural workers can know soil information in real time, and make timely decisions on whether to water or fertilize according to the soil information obtained and plant growth conditions, so as to promote plants to grow healthily and vigorously.

In fact, agricultural workers make many decisions every year, from production planning, pre-plant preparation, plant-period management, to harvesting. Most of these decisions are interlinked, and if there is a problem in any link, it may face the consequences of reducing production. Therefore, a large amount of relevant data is obtained through various sensors, and useful information is obtained through information extraction, and scientific decision-making based on the obtained information can greatly improve crop yield.
