Description

Technical Field

[0001] The utility model relates to the field of planting technology, and specifically to a photon sensor with an LCD and a radar ranging module. Background Art

[0002] In agriculture, measuring the photon flux density of photosynthetically active radiation (PPFD) is of great reference significance. PPFD refers to the photon flux density of photosynthetically active radiation per unit area per unit time, usually expressed in micromoles per square meter per second (μmol / m 2 / s). Measuring PPFD has important applications in agriculture. Light management: Understanding the light intensity received by plants is critical to plant growth and development. By measuring PPFD, agricultural producers can evaluate the intensity and distribution of light to optimize light management and ensure that plants receive enough photosynthetically active radiation to promote healthy growth; Light regulation: In modern agricultural production such as greenhouse cultivation and vertical farming, the use of artificial light sources can be regulated by measuring PPFD to ensure that plants receive appropriate light at different growth stages, thereby improving yield and quality; Research and experiments: Scientific research institutions and agricultural producers often need to conduct plant growth experiments and research. Measuring PPFD can help them understand the changes and responses of plant growth under different lighting conditions.

[0003] Currently, the existing photon sensors are divided into handheld and industrial types. Handheld: using light sensor modules and optical structures to perform single measurements, and displaying various data such as PPFD or spectrograms on the screen; Industrial: using light sensor modules and optical structures, plus 485 communication or other methods to receive instructions and upload data.

[0004] The disadvantages of the existing technology are: a. The existing handheld and industrial versions of photon sensors do not combine real-time display and data upload; b. The distance between the sensor and the light source has a great influence on the PPFD measurement, and currently it mostly depends on the experience of planting engineers. Utility Model Content
