[0031] Specifically, the display screen 51 and the indicator light 52 of the device can be observed externally, and the internal display screen 51 and the indicator light 52 can be protected to a certain extent from the influence of the external environment, such as dust, moisture, etc., so that the user can clearly see the working state of the device under different environmental conditions, and the usability and user experience of the device are improved.

[0032] Further, the PCB board 5 is provided with an Internet of Things communication module, and a connection port 23 is arranged on the side of the sealing detection shell 2, and an external antenna 7 electrically connected with the Internet of Things communication module is fixed in the connection port 23.

[0033] Specifically, the Internet of Things communication module transmits the pressure data through a mobile network signal, and the user can check the pressure in real time through a small program app, and when the pressure is abnormal, the device automatically triggers an alarm mechanism and pushes alarm information to the user through the app, so that the user can take corresponding measures according to the alarm prompt, such as checking whether the pipeline is blocked, leaking or adjusting the operation parameters of the related equipment, etc., so as to realize signal acquisition and transmission. For the prior art, the specific model of the Internet of Things communication module is not limited, and the external antenna 7 can significantly enhance the signal receiving and transmitting capability of the device, so as to ensure that the pressure detection data can be stably and accurately transmitted and the reliability of the Internet of Things communication is ensured.

During installation, the pressure sensor assembly 8 is tightly connected with the pipeline without leakage, and its detection end extends into the pipeline to contact the pressure source to be detected. Turn on the power supply of the device, and the pressure sensor assembly 8 starts to work, measures the pipeline pressure in real time and transmits the data to the PCB board 5. The Internet of Things communication module in the PCB board 5 transmits the pressure data through mobile network signal. Users can view the pressure situation in real time through the app. When the pressure is abnormal, the app will push alarm information to the user. The user can take corresponding measures according to the alarm prompt, such as checking whether the pipeline is blocked, leaking or adjusting the operation parameters of the related equipment. It is worth noting that the device needs to be checked every few days or weeks. Whether the color-changing silicone meets water discoloration can be directly observed through the transparent glass sheet 14, which can directly judge the waterproof condition inside the product, realize the visual monitoring of the waterproof condition, and ensure the sustainable operation of the device.
