[0002] The computer Internet of Things intelligent pressure sensor has the functions of data processing, self-diagnosis, self-compensation, online calibration, logical judgment, etc. It adopts the standard IEEE802.11 b / g / n network interface, and the application layer protocol is SCP-WIFI. It has good interchangeability and compatibility, and is suitable for all-weather collection and communication in the field or harsh environment. It can meet the pressure measurement in corrosive, impact, vibration and other places, and is suitable for meter reading systems. The pressure sensor has wireless communication function, which can realize the remote data real-time monitoring function.

[0003] The Chinese utility model patent with patent number CN212458724U discloses a pressure sensor based on computer Internet of Things. When in use, pinch the handle on the sleeve and slide it vertically, the sleeve moves up and rotates to the upper side of the device body, and the sleeve is moved down to be embedded in the full ring groove formed by the first outer plate and the second outer plate. The sleeve is sleeved on the outer side of the device body and the bottom end is connected with the first outer plate and the second outer plate by clamping. The sleeve plays a protective role to prevent the device body from being deformed by external collision; in addition, the first shell and the second shell are rotated, and the first shell and the second shell are sleeved on the outer side of the interface. When the first shell and the second shell are fitted, a limiting groove is formed, and the interface is located in the limiting groove. At this time, the limiting block is embedded in the fixed block, and the rubber pad covers the interface, which reduces the aging speed of the interface and avoids leakage.
