A sensor refers to an electrical component that can sense relevant parameters of a detected object and output a specific signal according to established public calculations. Its working principle is to rely on different natural effects (biological, chemical or physical, etc.) to convert various non-electrical resources of the detected object into a data electrical signal format. Sensors are a manifestation of high-end technology developed by modern science and technology. With the joint support of contemporary network technology and detection technology, sensors will surely demonstrate their powerful functions in various industries in future production.

Traditional agriculture has been eliminated due to outdated equipment. Nowadays, modern commercial agriculture armed with modern science, technology and equipment is quite competitive in our country. Among them, sensors play an irreplaceable and effective function in all aspects of the agricultural production process.

There are many types of temperature sensors, which can be divided into different types according to different sensing methods and sources. Currently, the following types are widely used in the production industry, including thermal resistance type, semiconductor type and thermocouple sensors. With the in-depth application of modern technology, more technologically advanced optical fiber sensors have emerged. Their main function is to detect, display and transmit temperature.

Its main working principle is the process of sensing and detecting atmospheric humidity, and then converting it into a power signal according to program rules. In various production industries, the more commonly used and widely used humidity sensors include the following types: electrolyte humidity sensors, MOS humidity sensors, ceramic humidity sensors and other models.

Its main task is to detect the amount of each component element in a specific gas medium and then convert it into electrical signal data. In various production industries, the more common types of sensors are as follows: combination potentiometer type, concentration cell type, semiconductor gas-sensitive type, etc.
