[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] Example 1

[0045] Please refer to Figures 1-4 One embodiment of this utility model provides a temperature and humidity sensor for livestock breeding, including: a housing 1, a circuit board 2, a sensor chip 3, a filter cover 4, a dust cap 5, and a protective sleeve 6;

[0046] The circuit board 2 is fixedly disposed inside the housing 1;

[0047] The sensor chip 3 is disposed at the first end of the circuit board 2, and the sensor chip 3 extends out of the housing 1;

[0048] The filter cover 4 is disposed on the circuit board 2 and covers the sensor chip 3 to prevent water droplets from falling into the surface of the sensor chip 3.

[0049] The dust cap 5 is connected to the end of the outer shell 1, and the sensor chip 3 and the filter cover 4 are housed inside the dust cap 5 to prevent dust from falling into the surface of the filter cover 4.

[0050] The protective sleeve 6 is connected to the outer casing 1 sleeve, and the protective sleeve 6 is configured to be detachably fitted onto the dust cap 5 to protect the sensor chip 3 during disinfection.

[0051] Understandably, sensor chip 3 is the core of the entire temperature and humidity detection process, typically employing capacitive or resistive sensing elements. Taking humidity monitoring as an example, in a livestock farming environment, when moisture in the air comes into contact with sensor chip 3, it alters the chip's electrical characteristics. Sensor chip 3 converts this change into a measurable electrical signal and transmits it to circuit board 2. The signal is amplified by the amplifier circuit on circuit board 2 and then transmitted to external monitoring equipment via communication harness 7, thus achieving temperature and humidity monitoring. The specific selection of the sensor chip and circuit board 2, as well as the amplification and conversion of the electrical signal, can all utilize existing mature and compatible solutions; the above is merely a principle introduction.

[0052] The temperature and humidity sensor for livestock farming provided by this utility model can achieve the following technical effects:

[0053] 1. The filter cover 4 is mainly used to prevent water droplets from falling directly onto the surface of the sensor chip 3. It is made of a hydrophobic material with a microporous structure. When water droplets in the air fall onto the filter cover 4, the water droplets will be blocked on the outside of the filter cover 4 due to the hydrophobicity of the material, while water vapor molecules can pass through the filter cover 4 to reach the sensor chip 3. This can prevent water droplets from damaging the sensor chip 3 or interfering with the accuracy of temperature and humidity measurement.

[0054] 2. Understandably, if dust accumulates on the filter cover 4, it will clog the micropores of the filter cover 4 and affect the passage of water vapor. Therefore, the dust cap 5 is used to allow air and water vapor to pass through, while effectively blocking larger dust particles, thereby ensuring that the filter cover 4 can work normally and ensuring that the sensor chip 3 can accurately sense temperature and humidity.

[0055] 3. The protective cover 6 can be placed over the dust cap 5 during disinfection. It prevents the disinfectant from directly contacting the sensor chip 3 and avoids any adverse effects on its performance. It is also detachable, allowing for easy removal after disinfection without affecting the sensor's normal measurement operation.

[0056] Example 2

[0057] Please refer to Figures 1-6 Based on Embodiment 1, the outer shell 1 includes a tubular body 11, a first cover 12, and a second cover 13;

[0058] The first cover 12 is disposed at the first end of the tubular body 11, and the circuit board 2 is snapped and fixed to the first cover 12;

[0059] The second cover 13 is disposed at the second end of the tubular body 11. A through hole is provided at the center of the second cover 13. A wire harness 7 is connected to the other end of the circuit board 2 relative to the sensing chip 3. The wire harness 7 passes through the through hole to the outside of the tubular body 11.

[0060] In one implementation scenario, the first cover 12 is provided with external threads, and the first cover 12 is threadedly connected to the tubular body 11 and the dust cap 5;

[0061] The second cover 13 is provided with internal threads, and the outer side of the second cover 13 is provided with anti-slip texture.

[0062] In one implementation scenario, the first cover 12 is a cylindrical structure composed of two arc-shaped units. The interior of the cylindrical structure has a positioning protrusion, and the edge of the circuit board 2 is provided with a positioning notch corresponding to the positioning protrusion.

[0063] In one implementation scenario, sealant is injected at the connection between the first cover 12 and the circuit board 2 to form a sealing filler.

[0064] In one implementation scenario, a waterproof sealing ring is provided at the connection between the second cover 13 and the wire harness 7.

[0065] The temperature and humidity sensor for livestock farming provided by this utility model can achieve the following technical effects:

[0066] 1. The connection between the first cover 12 and the circuit board 2 is filled with sealant to form a sealed filler, which can effectively prevent moisture and dust from entering the tubular body 11. The connection between the second cover 13 and the wire harness 7 is provided with a waterproof sealing ring, which further enhances the waterproof performance of the sensor, prevents moisture from entering the tubular body 11 along the wire harness 7, protects the circuit board 2, ensures that the sensor can work normally in a humid environment, and improves the stability and reliability of the sensor.

[0067] 2. The first cover 12 is connected to the tubular body 11 and the dust cap 5 by threads, and the second cover 13 is also connected to the tubular body 11 by threads. This connection method is firm and reliable, which can ensure that the components will not easily loosen during use and ensure the overall structural stability of the sensor. In addition, the circuit board 2 is snapped and fixed to the first cover 12, and the positioning protrusion inside the first cover 12 corresponds to the positioning notch on the edge of the circuit board 2. This design can keep the circuit board 2 in an accurate position during installation and use, and prevent the circuit board 2 from shifting or shaking.

[0068] Example 3

[0069] Please refer to Figures 1-7Based on Embodiment 1 or Embodiment 2, the filter cover 4 includes a mounting bracket 41 and a waterproof and breathable membrane 42. The mounting bracket 41 is snapped to the circuit board 2. The mounting bracket 41 is provided with an opening corresponding to the sensor chip 3. The waterproof and breathable membrane 42 is disposed on the opening of the mounting bracket 41. The waterproof and breathable membrane 42 is configured to prevent water droplets from falling onto the surface of the sensor chip 3.

[0070] In one implementation scenario, one end of the protective sleeve 6 is provided with a traction rope 61, and the other end of the traction rope 61 is elastically sleeved on the outer shell 1 through a fixing ring 62.

[0071] In one implementation scenario, the protective sleeve 6 is a flexible material protective sleeve, specifically a flexible material protective sleeve made of silicone, so that the protective sleeve 6 fits tightly against the outer side of the outer shell 1.

[0072] Understandably, the waterproof and breathable membrane 42 is a polymer film with a special microporous structure. Its function is based on the characteristic that water vapor molecules are smaller than water droplets; the waterproof and breathable membrane 42 allows water vapor molecules to pass through but not water droplets. This allows for the measurement of humidity in the air, thus achieving waterproofing. When water exists in the form of water vapor, the water molecules are small and can pass through the micropores of the waterproof and breathable membrane 42, allowing for air permeability. However, when water vapor condenses into water droplets, the particles become larger, and due to the surface tension of the water droplets, water molecules cannot easily pass through the micropores, thus preventing moisture penetration and achieving a waterproof effect. The waterproof and breathable membrane 42 can be purchased using existing mature supporting solutions; the above is only an introduction to the principle.

[0073] The temperature and humidity sensor for livestock farming provided by this utility model can achieve the following technical effects:

[0074] 1. The mounting bracket 41 is connected to the circuit board 2 by a snap-fit, which facilitates production and assembly; the waterproof and breathable membrane 42 covers the sensor chip 3 to prevent water droplets from falling directly on the chip surface, thus avoiding damage to the sensor chip 3 or interference with the accuracy of humidity measurement. At the same time, it allows water vapor to pass through without affecting the sensor chip 3's sensing of humidity.

[0075] 2. The flexible material protective sleeve 6 fits tightly against the outer side of the outer shell 1, effectively preventing disinfectants or high-pressure water from entering the sensor during cleaning or disinfection, further enhancing the sensor's durability. Furthermore, the flexible material protective sleeve 6 ensures a tight fit against the outer side of the outer shell 1. This elastic connection method can adapt to certain vibrations and displacements, preventing the protective sleeve 6 from loosening or falling off due to vibration or external forces during use, ensuring that the protective sleeve 6 is always tightly fitted onto the outer shell 1, providing reliable protection for the sensor.

[0076] Example 4

[0077] In one embodiment of this utility model, an environmental monitoring device is also provided, including a temperature and humidity sensor for livestock farming as described in any of the above embodiments.

[0078] The environmental monitoring equipment provided by this utility model can achieve the following technical effects:

[0079] 1. By setting a filter cover 4 above the sensor chip 3, and placing both the sensor chip 3 and the filter cover 4 inside the dust cap 5, the dust cap 5 filters out large particles of dust from the farm, preventing dust from contaminating the sensor chip. The filter cover 4 also isolates water droplets that enter the dust cap 5, because water vapor molecules are smaller than water droplets, allowing water vapor molecules to pass through but preventing water droplets from passing through. This allows for the measurement of humidity in the air, achieving waterproofing and avoiding measurement deviations caused by water droplet adhesion.

[0080] 2. By injecting sealant at the connection between the first cover 12 and the circuit board 2 to form a sealing filler, the gap between the first cover 12 and the circuit board 2 is filled; and a waterproof sealing ring is provided at the connection between the second cover 13 and the wire harness 7, thereby improving the waterproof level of the internal circuit structure of the sensor.

[0081] 3. A traction rope 61 is provided at one end of the protective sleeve 6, and the other end of the traction rope 61 is elastically sleeved on the outer shell 1 through a fixing ring 62. The protective sleeve 6 is made of flexible material so that the protective sleeve 6 fits tightly against the outer side of the outer shell 1. During cleaning or disinfection, the protective sleeve 6 can be elastically sleeved on the first end of the tubular body 11 to better protect the sensor chip 3 and filter cover 4 inside the dust cap 5.

[0082] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
