[0031] like Figures 1 to 5As shown, this embodiment of an agricultural greenhouse environment monitoring sensor includes a main body 1, which has a cavity 11 of a certain length inside. The main body 1 is made of a transparent material to facilitate light transmission. Specifically, the main body 1 is formed into a cylindrical tube with a hollow internal space and is made of a transparent synthetic resin material. The cavity 11 contains a moving component 2, an illumination component 3, a front reflector component 4, a camera component 5, and a rear reflector component 6. The moving component 2 moves along the axial direction of the main body 1. The illumination component 3 emits light to illuminate the soil, facilitating image acquisition by the camera component. The front reflector component 4 is positioned opposite to the illumination component 3, reflecting the light emitted by the illumination component 3 out of the main body 1. The front reflector component 4 and the illumination component 3 are connected by a connecting rod 7. The front reflector component 4 is connected to the moving component 2 and moves with the moving component 2, allowing the front reflector component 4 and the illumination component 3 to move synchronously, thereby adjusting their positions within the cavity 11. The camera component 5 is connected to the front reflector component 4 via a connecting rod 7, allowing it to move synchronously with the front reflector component 4. The camera component 5 receives reflected light to form an image for judging soil conditions. The rear reflector component 6 is connected to the camera component 5 via the connecting rod 7, enabling the rear reflector component 6 to move. The rear reflector component 6 receives external light from the main body and reflects the light along the axis of the main body 1 to the camera component 5, allowing the camera component 5 to receive the light. This technical solution allows the main body 1 to be inserted into the greenhouse soil, and the soil conditions can be analyzed through photographs. By moving component 2 and connecting rod 7, the positions of the lighting component 3, front reflector component 4, camera component 5, and rear reflector component 6 can be adjusted synchronously, allowing for the acquisition of images from multiple positions and improving judgment accuracy. In use, the light emitted by the lighting component is reflected by the front reflector component 4 and enters the soil through the main body, providing illumination. The light reflected back to the main body is reflected by the rear reflector component 6 and received by the camera component to form an image. This technical solution allows for the formation of images within the soil, and multiple positions can be adjusted to acquire images from different locations.

[0032] Furthermore, the front reflector assembly 4 includes a first plate 41 and a first reflector 42 disposed on the first plate 41. The first plate 41 is connected to the moving assembly 2 and can be moved by the moving assembly 2, thereby moving the first reflector 42. The surface of the first reflector 42 has an arc-shaped concave surface 421, allowing the received light to be reflected outwards. The camera assembly 5 includes a second plate 51 and a camera 52. The lighting assembly 3 is disposed on the first side 511 of the second plate 51 and opposite to the first reflector 42. The lighting assembly 3 includes several lamps 31, which are used to emit light and can use existing light-emitting elements such as LEDs. The camera 52 is disposed on the second side 512 of the second plate 51, opposite to the lamps 31, so that it does not directly receive light from the lamps 31. The rear reflective assembly 6 includes a third plate 61 and a second reflector 62 disposed on the third plate 61. The second reflector 62 is disposed opposite to the camera 52, so that the light reflected by the second reflector 62 can be directed toward the camera 52. The surface of the second reflector 62 has a convex surface. The first, second, and third plates are arranged in parallel and connected by a connecting rod 7, so that the three plates can move synchronously. The second plate 51 is disposed between the first and third plates. The main body 1 is cylindrical, and the first to third plates are circular, thereby adapting to the cross-sectional shape of the main body and facilitating its movement within the receiving cavity 11. The moving assembly 2 includes a moving plate 21, a rotating rod 22, and a motor 23. The moving plate 21 is threadedly connected to the rotating rod 22. The rotating rod 22 can be a screw. The motor 23 is connected to the rotating rod 22 and drives the rotating rod 22 to rotate. After the rotating rod 22 rotates, the moving plate 21 can move along the axial direction of the rotating rod 22. The rotating rod 22 is disposed in the middle of the main body 1 along the axial direction of the main body 1. A circuit board 8 is provided between the movable plate 21 and the first plate 41. The circuit board 8 is electrically connected to the lighting component 3 and the camera component 5 respectively for power supply and signal processing. At the same time, it enables the first plate 41 to be connected to the movable plate 21, thereby driving the first to third plates to move through the movable plate 21. A guide rod 12 is provided in the receiving cavity 11. The two ends of the guide rod 12 are set on the fixed plates at both ends of the main body. The guide rod 12 passes through the movable plate and the first to third plates, making the movement more stable.

[0033] Furthermore, a detection component 9 is provided at one end of the main body 1, located above the soil, for detecting the greenhouse environment. The detection component 9 includes a power supply 91, a control module 92, and several sensors 93. The sensors 93 are electrically connected to the power supply 91 and the control module 92, respectively. The power supply provides power and can be a rechargeable battery. The control module 92 and the power supply 91 are also electrically connected to the circuit board 8 for receiving signals from the circuit board and providing power. The control module is used for current and signal control, and can be equipped with a wireless communication unit for signal transmission and reception. The sensors detect environmental conditions; specifically, they may include temperature sensors, humidity sensors, and light sensors. A solar panel 94 is provided at the end of the main body, which can charge the battery, thereby improving the battery's endurance. Alternatively, a charging interface can be provided on the outside of the main body for manual external power supply or charging.

[0034] The agricultural greenhouse environment detection sensor of this embodiment can detect the environment inside and above the soil, thereby comprehensively judging the status of plant growth-related factors and enabling real-time detection. In addition, the position of the detection component below the soil can be adjusted to acquire more images from different positions, thereby improving the accuracy of the judgment.
