Soil moisture sensor for greenhouse detection

Abstract

The present invention belongs to the technical field of greenhouse detection, in particular to a soil moisture sensor for greenhouse detection. The soil moisture sensor comprises a sensor body and a protective casing; the sensor body is arranged in the protective casing; a connecting plate is welded on one side of the sensor body; one end of the connecting plate extends to the outer side of the protective casing; one end of the connecting plate arranged outside the protective casing is welded with a pulling handle; the connecting plate is internally provided with a mounting slot; the bottom ofthe mounting slot is fixedly provided with an electromagnet; the mounting slot is movably provided with a display; one side of the protective casing is fixedly provided with a rotating bracket; a rotating plate is arranged on one side of the protective casing through the rotating bracket; and a detecting probe and a collecting cylinder are arranged on one side of the sensor body. According to thetechnical scheme of the present invention, the soil moisture sensor for greenhouse detection has a reasonable structure and a simple operation, use of the display is flexible, and frequent cleaning is not required; the soil moisture sensor has a soil collecting function; and when the soil moisture sensor is not in use, the detecting probe can be retracted to the protective casing, so that the protection effect on the sensor body is better, and the soil moisture sensor is portable.

Description

technical field [0001] The invention belongs to the technical field of greenhouse detection, and in particular relates to a soil moisture sensor for greenhouse detection. Background technique [0002] Greenhouse, also known as greenhouse, is a facility with light transmission and heat preservation properties, used to cultivate plants, especially in seasons that are not suitable for plant growth, it can provide greenhouse growth period and increase production, and is mostly used in low temperature seasons. Vegetables, flowers, forest trees and other plant cultivation or seedling cultivation can meet people's needs for eating off-season fruits and vegetables. However, during the cultivation process in greenhouses, the requirements for soil moisture are high, and planters need to measure soil moisture frequently.

[0002] Greenhouse, also known as greenhouse, is a facility with light transmission and heat preservation properties, used to cultivate plants, especially in seasons that are not suitable for plant growth, it can provide greenhouse growth period and increase production, and is mostly used in low temperature seasons. Vegetables, flowers, forest trees and other plant cultivation or seedling cultivation can meet people's needs for eating off-season fruits and vegetables. However, during the cultivation process in greenhouses, the requirements for soil moisture are high, and planters need to measure soil moisture frequently. This requires the use of soil moisture sensors. The internal technology of existing soil moisture sensors has been relatively sound, and can basically measure more accurate data, which can meet the current use needs.

[0003] However, the external structure of the existing soil moisture sensor is relatively simple, and there are still three problems that need to be improved:

[0004] 1. The external structure of the existing soil moisture sensor is too simple. It only wraps each electronic component with a simple shell. The detection probe of the soil moisture sensor is directly exposed, and the probe needs a certain length to ensure the detection accuracy. It is exposed and easy to stab the user, and it is not easy to carry;

[0005] 2. The display part of the existing soil moisture sensor is generally relatively fixed, mostly directly installed on the outer wall of the sensor body, and because the soil moisture sensor needs to be buried underground as a whole when in use, it is easy to cause a certain negative impact on the display part;

[0006] 3. The existing soil moisture sensor has a single function and does not have the function of soil collection
