[0026] Example 1

[0027] A suspended multi-factor environmental detector, such as Figure 1As shown, it includes a transparent cover 1, a light sensor 6, a solar panel 7, a fan 8, a temperature and humidity sensor 10 and a main board which are coaxially arranged in sequence. The light sensor 6, the solar panel 7, the fan 8, the temperature and humidity sensor 10 are electrically connected to the main board. The light sensor 6 and the solar panel 7 are located in the transparent cover 1. The temperature and humidity sensor 10 is arranged on the main board and is located in a protective shell with the main board. The protective shell is provided with ventilation holes. The solar panel 7 provides power for the main board and the fan 8. The temperature and humidity sensor 10 can have its own power supply or use the power provided by the solar panel 7. The light sensor 6 senses the light intensity and transmits it to the main board. When the light intensity reaches a preset threshold, the main board controls the fan 8 to start. The transparent cover 1 is provided with ventilation holes for internal and external air circulation to improve the detection accuracy of the light sensor. In some embodiments, in order to prevent the sunlight from affecting the temperature and humidity sensor 10 and the mainboard and other equipment below, at least one layer of hollow louvered box 3 is provided between the solar panel 7 and the fan 8, and the diameter of the louvered box 3 is larger than the diameter of the protective shell, so as to avoid direct sunlight and reduce the influence of heat radiation. In order to further reduce the influence of solar heat radiation, in some embodiments, a heat-insulating bottom plate 2 is provided between the solar panel 7 and the louvered box 3, and the heat-insulating bottom plate 2 is provided with air holes.

[0028] The temperature and humidity sensor 10 is located in a protective housing, which includes an upper housing 4 and a lower housing 5. The bottom of the lower housing 5 is a hyperboloid convex shape, which is used to accommodate the temperature and humidity sensor 10. In order to further protect the temperature and humidity sensor 10, a waterproof and breathable membrane is provided on the outside of the temperature and humidity sensor 10 to protect the temperature and humidity sensor 10.

[0029] In order not to affect the detection accuracy of the temperature and humidity sensor 10 in the protective shell, a plurality of ventilation holes are arranged in an array around the lower shell 5 to exchange the external air with the internal air in a timely manner, thereby ensuring that the temperature and humidity sensor 10 detects the external air and reducing errors.

[0030] In order to accommodate more detection elements, the lower shell 5 is provided with an external sensor interface, to which a new sensor can be connected as needed. The external sensor interface is closed with a sealing cover when not in use.

[0031] In terms of installation, the transparent cover 1 of the utility model is provided with a hanging hole on the top to facilitate hanging the detector in a suitable place. In addition, a mounting hole can also be provided on the lower shell 5 for installing a cross arm bracket.

[0032] The multi-factor environment detector of this embodiment contains a temperature and humidity sensor, a light sensor and a silent low-speed fan. The outer shell includes a transparent cover 1 with air holes, an insulating bottom plate 2 with air holes, two layers of large-diameter louvered boxes 3, an upper shell 4 and a lower shell 5 for protecting the mainboard, wherein the bottom of the lower shell 5 is a hyperboloid convex, which can well protect the temperature and humidity module. The layout of the air holes around it ensures that the temperature and humidity module can detect the changes in the ambient temperature and humidity, and the temperature and humidity sensor 10 is also provided with a waterproof breathable membrane on the outside, which plays a dustproof and waterproof role. The upper half of the entire shell has a large diameter to meet the layout of the solar panel 7 and the light sensor 6; the middle is a hollow louvered box shape with good ventilation effect; the lower half has a small diameter to avoid direct sunlight and reduce the influence of thermal radiation. The temperature and humidity sensor with a waterproof breathable membrane is vertically welded on the mainboard, as far away from the main heat source as possible, and with the air holes of the shell, the air outside the shell is introduced into the shell through the air holes, ensuring that the temperature and humidity sensor detects the air outside the shell. When the sunlight reaches a certain intensity, the fan 8 starts to blow air slowly upwards to form an air flow from bottom to top. On the one hand, it can help dissipate heat between the solar panel 7 and the insulation base plate 2 to prevent heat accumulation in the solar panel 7 and affect the detection of the sensor. On the other hand, the fan 8 drives the air to flow from bottom to bottom, which can directly lead the air to be tested in the outer shell to the temperature and humidity sensor, making the test results closer to the actual air indicators outside the shell and the test structure more accurate.

[0033] The device can be used in multiple scenarios. The hanging hole reserved in the top transparent cover 1 can be directly hung with a hook or fishing line. The lower shell 5 has reserved installation holes to meet the installation of the cross arm bracket. The reserved external sensor interface uses an onboard aviation socket, which can be protected with a corresponding sealing cover when not in use. The SIM and Type C ports are protected by soft rubber plugs made of gas phase rubber and can be used repeatedly.

[0034] Example 2

[0035] Compared with Example 1, Example 2 adds a carbon dioxide sensor 9 on the basis of Example 1. In order to prevent the two sensors from affecting each other, the temperature and humidity sensor 10 is vertically arranged below the main board in this embodiment, and the carbon dioxide sensor 9 is located above the main board. Figure 2 shown.

[0036] In summary, the utility model has at least the following technical effects:

[0037] 1. Accurately sense ambient temperature and humidity;

[0038] 2. IPX5 waterproof, anti-sunlight and ventilation to reduce heat accumulation;

[0039] 3. Structure that is convenient and quick to deploy.

[0040] It is understandable that in order to make the present invention adapt to more detection requirements, other sensors may be added, such as pressure sensors, odor sensors, smoke sensors, etc.

[0041] It should be noted that, for the aforementioned embodiments, for the sake of simplicity, they are all described as a series of action combinations, but those skilled in the art should be aware that the present application is not limited by the described order of actions, because according to the present application, certain steps can be performed in other orders or simultaneously. Secondly, those skilled in the art should also be aware that the embodiments described in the specification are all preferred embodiments, and the actions and modules involved are not necessarily required by the present application.

[0042] The above specific implementation methods further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
