Description

Technical Field

[0001] This utility model belongs to the field of sensor technology, specifically a plant root soil monitoring sensor. Background Technology

[0002] The six essential elements for plant growth are light, water, temperature, air, soil, and nutrients. These six elements are interconnected and indispensable. Soil moisture is closely related to root growth and is a crucial factor limiting root development in trees, possessing an irreplaceable role. Soil moisture conditions affect root growth in multiple ways. A well-aerated and moist soil environment is conducive to root growth; the optimal soil moisture content for root growth is 60%–80% of maximum water holding capacity. The suitable soil temperature for plant root growth is 20℃ to 22℃; root growth is inhibited below 12℃.

[0003] Therefore, in order to facilitate the detection of soil conditions around plant roots, existing technologies provide some sensor components to monitor the soil around plant roots. For example, patent document CN106197565A describes a multifunctional detection device and service system for the green plant growth environment. By setting air temperature and air humidity sensors inside the housing and soil moisture sensors at the lower end of the housing, it can quickly and accurately detect soil moisture, air temperature, and air humidity for plant growth. However, when this detection device is used, the sensors need to be inserted into the soil. The sensor probes will wear out during long-term use. Since the existing probes and sensors are fixedly connected, it is inconvenient to replace them quickly. Utility Model Content
