Agricultural product planting temperature and humidity sensor for intelligent agricultural system

Abstract

The invention discloses an agricultural product planting temperature and humidity sensor for an intelligent agricultural system, and belongs to the field of sensors. The agricultural product planting temperature and humidity sensor comprises a greenhouse and an adjusting device, wherein the adjusting device is vertically mounted in the greenhouse, the adjusting device comprises a mounting frame and a shell, the section of the shell is arranged in a segmental cambered surface shape, the mounting frame is arranged corresponding to the segmental surface of the shell and fixed to the inner wall of the greenhouse, a square groove is vertically formed in the side wall of the shell, a distance adjusting base is arranged in the shell, a temperature and humidity sensor body is arranged on the distance adjusting base, a moisture absorption assembly is clamped and embedded in one side of the temperature and humidity sensor body, the distance adjusting base is arranged to be a circular plate, three planar segmental surfaces are arranged on the circular plate distance adjusting base along the annular surface array, and the planar segmental surfaces and the upper arc surface of the distance adjusting base are arranged alternately, so that the temperature and humidity sensor body can ascend or descend, and real-time detection of the temperature and humidity in air flow in the height or two directions of the bottom in the greenhouse is facilitated.

Description

Technical field [0001] The present invention relates to the field of sensors, and more particularly to the temperature humidity sensor for agricultural planting for intelligence agricultural systems. Background technique [0002] Smart agriculture is a smart economy in agriculture, or the specific performance of intelligence economy in agriculture. Wisdom Agriculture is an important part of the smart economy; for developing countries, smart agriculture is the main components of smart economy. It is the main way to develop in developing countries to eliminate poverty, realize the advantage, and the economic development is later, realize the main way of catching up the strategy. . [0003] The temperature and humidity sensor is multi-temperature humidity integrated probe as a temperature and temperature and humidity signals, and is processed by voltage regulatic filtering, operational amplification, nonlinear correction, V / I conversion, constant current, and reverse protection.

AI Technical Summary

Problems solved by technology

[0003] Temperature and humidity sensors mostly use temperature and humidity integrated probes as temperature measuring elements to collect temperature and humidity signals and process them through voltage stabilization filtering, operational amplification, nonlinear correction, V / I conversion, constant current and reverse protection circuits. Finally, it is converted into a current signal or a voltage signal output that is linearly related to temperature and humidity, and can also be directly output through the main control chip such as 485 or 232 interfaces. In agricultural greenhouses, from the cultivation of flowers, vegetables, fruits and grains, When it comes to the breeding of pigs, cattle and sheep, you can see the "figure" of the hard work of the temperature and humidity sensor. It is by the temperature and humidity sensor that regulates and controls the environmental conditions of crop production day and night that human beings can eat without looking at the face of God. Therefore, The emergence of temperature and humidity sensors is a revolutionary development of conventional agriculture and a transformation of high-yield, high-efficiency, high-quality and technology-intensive agriculture. However, in some agricultural greenhouses, some agricultural products have strict requirements on temperature and humidity. Among them, the crops cultivated in glass greenhouses are mostly planted in vertical arrangement. Because the height of glass greenhouses is higher, the internal air flow is stronger than that of arched greenhouses. Traditional temperature and humidity sensors use multi-point Distributed in the shed, weak for high-altitude and low-altitude sensing
