Description

Technical Field

[0002] A wireless sensor is a device that combines a sensor unit, a processor, and a wireless communication module. It can measure, detect, and monitor a variety of information, and send data to a receiver or other device through wireless communication technology. Wireless sensors are widely used in experimental monitoring, environmental monitoring, and other fields.

[0003] For example, a low-power wireless temperature sensor recorded in the patent with patent announcement number CN 219736622 U provides buffer protection for the temperature sensor through the cooperation of a spring, a buffer rod and a buffer pad, thereby preventing damage to the temperature sensor body during vibration. This low-power wireless temperature sensor uses a spring to reduce shock. The spring produces elastic deformation multiple times and rapidly during the shock reduction process, causing uneven pressure on the surface of the temperature sensor. Long-term use may cause damage to the temperature sensor body.
