Description

Technical Field

[0001] The utility model relates to the field of sensor structures, in particular to a sensor structure for improving signal gain. Background Art

[0002] With the development of science and technology, traffic flow statistics also indirectly reflect the level of urban development. At present, traffic flow signal sensors are often used in traffic flow monitoring, but there is a lack of stable structures to match them on the market. In normal installation, screws are often used to install them directly on the mounting rods. This installation method is prone to shaking or jittering during later use, which is not conducive to the normal use and operation of the equipment. When the sensor of the equipment collects signals, frequent shaking will greatly affect the collection effect. Utility Model Content
