Description

Technical Field

[0001] The utility model relates to the technical field of smart agriculture, and in particular to an agricultural greenhouse air temperature and humidity sensor for smart agriculture. Background Art

[0002] Sensors are widely used in agricultural production. They can help farmers achieve refined management and improve agricultural production efficiency and quality. These sensors can measure various parameters in the environment and help farmers better understand the environment and needs of crop growth. Through the combination of Internet of Things technology and intelligent algorithms, farmers can achieve remote monitoring and automatic control, manage and protect crops more efficiently. The air temperature and humidity sensor is one of the sensors. It monitors air temperature and humidity in real time. After measuring the temperature and humidity, it is converted into electrical signals or other required forms of information output according to certain rules. The air temperature and humidity sensor plays a vital role in agricultural production.

[0003] The authorization document with publication number CN213543626U mentions an air temperature and humidity sensor for smart agriculture in an agricultural greenhouse. The air temperature and humidity sensor for smart agriculture in an agricultural greenhouse can conveniently detect the humidity inside the greenhouse, provide a better growth environment for crops, improve quality and reduce time, but there are still certain defects and shortcomings that need to be optimized. The specific defects and shortcomings are as follows: The air temperature and humidity sensor for smart agriculture in an agricultural greenhouse can only monitor the air at a single height inside the greenhouse in real time. In fact, inside the greenhouse, due to the movement law of airflow and the uneven temperature distribution, the height of the greenhouse will affect the temperature. Normally, the temperature at the top of the greenhouse will be relatively low, but when the height of the greenhouse increases, due to the rise of hot air and the sinking of cold air, the movement law of airflow inside the greenhouse will also change, resulting in the temperature at the bottom of the greenhouse to rise and the temperature at the top of the greenhouse to drop. Therefore, when the air at a single height in the greenhouse is monitored in real time, deviations are prone to occur, which is not conducive to the precise control of the ambient temperature of crops.

[0004] Therefore, it is particularly important to design an agricultural greenhouse air temperature and humidity sensor for smart agriculture to solve the above-mentioned defects. Utility Model Content
