Description

Technical Field

[0001] The utility model relates to the technical field related to sensors, in particular to a biological micro-motion sensing device. Background Art

[0002] The biological micro-motion sensing device is mainly a living body presence sensor, which is equipped with electronic components for emitting microwaves and receiving signals. Electromagnetic microwaves are emitted by the transmitting antenna, and then the electromagnetic waves received by the receiving antenna are analyzed. The micro-motion signals are collected, judged, filtered, and a series of other processing are performed to obtain results to determine whether there are signs of micro-motion in the surrounding environment.

[0003] Existing biological micro-motion sensing devices are generally used in induction lamps and alarm detection devices. In lighting circuits, they sense whether someone is passing by, thereby controlling the switch of the light. When the person leaves, the light goes out to save electricity. In alarm devices, biological intrusion detection is realized. However, existing biological micro-motion sensing devices are generally fixed directly with bolts. When repairing and replacing, many sets of bolts need to be removed and then retightened. The installation and disassembly are very cumbersome, and the detection range angle is small, and the false alarm rate is high. Utility Model Content

[0033] The biological micro-motion sensing device is mainly a living body presence sensor. It transmits electromagnetic microwaves through a transmitting antenna, and then analyzes the electromagnetic waves received by a receiving antenna. It collects, judges, and filters the micro-motion signals to determine whether there are signs of micro-motion in the surrounding environment. It is generally used in induction lamps to control the switch of the lights. The lights will turn off when people leave, so as to save electricity.

[0034] However, the existing biological micro-motion sensing devices are generally fixed directly with bolts. When repairing or replacing, many groups of bolts need to be removed and then tightened again. The installation and disassembly are very cumbersome and have certain limitations.

[0035] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a biological micro-motion sensing device.
