Problems solved by technology

However, when there is a medium such as a wood board or a plasterboard between the sensor and the human body, the infrared sensor and the ultrasonic sensor cannot normally detect the movement of the human body. In addition, the infrared sensor and the ultrasonic sensor are also vulnerable to heat sources, Interference from light sources and radio frequency radiation, etc., makes this type of presence sensor only usable in a small range

Abstract

The invention discloses a presence inductor. The presence inductor comprises an induction component and a shell, wherein the power supply input end of a power supply management module is connected with a mains supply; the power supply input end of a microwave induction module is connected with the power supply output end of the power supply management module; the working frequency band of the microwave induction module is 2.75 GHz to 2.9 GHz; the induction component is arranged in the shell; and the shell is provided with a torsion spring convenient to install. According to the presence inductor disclosed by the invention, the reaction speed is high, the sensitivity is high, the induction area is wide, the presence inductor is not disturbed by temperature, airflow, dust, smoke and the like, and the stability is high; and moreover, the shell adopts the installation structure of the torsion spring, so that the operation is convenient and fast during installation, the structure is simple,and the cost is saved.

Description

technical field [0001] The present invention relates to the field of induction technology, in particular to a presence sensor. Background technique [0002] At present, the presence sensors on the market mainly use infrared rays and ultrasonic waves to detect the movement of the human body and then control the electrical appliances. However, when there is a medium such as wood or gypsum board between the sensor and the human body, the infrared sensor and ultrasonic sensor cannot detect the movement of the human body normally. In addition, the infrared sensor and ultrasonic sensor are also vulnerable to heat sources, Interference from light sources and radio frequency radiation makes such presence sensors only available in a small range. SUMMARY OF THE INVENTION [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention proposes a presence sensor, which can detect the presence of a human ...
