Description

Technical Field

[0001] The utility model relates to the technical field of sensors, and more specifically to an integrated sensor sealing structure. Background Art

[0002] On one device, multiple sensors with the same function are often required to run synchronously. The current connection method of the sensors is that the sensors are connected to the devices separately. Multiple connection ports need to be set on the devices to realize the installation of the sensors, and multiple interfaces are used. During the sensor installation process, they need to be installed independently, and the operation is relatively cumbersome.
