I. Introduction
With the rapid development of smart home, radar module technology has been widely used in the field of human sensing switch with its unique advantages. This paper aims to analyze the technical specifications of the radar module and the wiring diagram of the human body sensor switch in detail, so as to provide useful reference for smart home enthusiasts and technicians.
Ii. Overview of radar module technology
Radar module is a device that uses electromagnetic wave to measure distance and speed, and its core components include transmitter, receiver and signal processing circuit. In the field of smart home, the radar module achieves accurate detection of the human body by transmitting specific frequency electromagnetic waves and receiving signals reflected back by the human body. This non-contact detection method not only avoids the problem that traditional infrared induction is susceptible to environmental interference, but also has higher sensitivity and stability.
Three, radar module technical specifications
Operating frequency: The operating frequency of the radar module is one of the important parameters of its performance. Different operating frequencies correspond to different detection distances and accuracy. When selecting the radar module, it is necessary to determine the appropriate operating frequency according to the actual application scenario and requirements.
Detection distance: Detection distance refers to the large distance that the radar module can accurately detect the human body. This parameter is affected by many factors such as operating frequency, transmitting power and receiving sensitivity. In smart homes, it is usually necessary to determine the required detection distance based on the room size and layout.
Detection Angle: The detection Angle determines the detection range that the radar module can cover. A wider detection Angle can provide a wider monitoring area, but it can also lead to an increased rate of false positives. Therefore, when selecting the radar module, the relationship between the detection Angle and the false alarm rate should be balanced according to the actual demand.
Power consumption and stability: Power consumption is an important indicator to measure the energy efficiency of radar modules, and stability is related to its long-term reliability. An excellent radar module should have a high degree of stability while maintaining low power consumption to meet the needs of long-term operation of smart home systems.
