Chapter One: the principle analysis of radar human body sensing switch

1.1 What is Radar body sensing Switch

Radar human sensing switch is a kind of electrical switch which realizes automatic sensing by using radar technology and human infrared radiation principle. It can detect the movement of the human body and control the corresponding electrical equipment according to the position and dynamic changes of the human body.

1.2 Working Principles and Basic Functions

The radar body sensing switch uses the principle of radar wave propagation and reflection to sense the changes of the surrounding environment by transmitting and receiving radar waves. When a human body enters the detection range, the radar wave will be reflected by the human body, and the sensor will trigger the switch after receiving the reflected wave, so as to control the switching state of the lighting, music playback and other devices.

1.3 Comparison with other types of sensors

Compared to other types of sensors, such as infrared sensors and ultrasonic sensors, radar body sensing switches have the following advantages:

- High sensitivity: The radar human sensing switch has a wider range of sensing to the human body and can achieve more accurate sensing.

- Low power consumption: Due to the use of radar waves for induction, the energy consumption of the radar human sensor switch is relatively low when working.

- Long life: Radar sensors usually have a long life and can be used stably for a long time.

2.1 What is the Three-wire connection

The radar human body sensing switch adopts three-wire connection method, which is divided into fire line (L), zero line (N) and switch line (S). Among them, the live line and the neutral line are connected to the power supply, while the switch line is connected to the electrical equipment that needs to be controlled.

2.2 Materials required for assembly

When performing the three-wire connection of the radar human sensor switch, the following materials need to be prepared:

- Radar body sensing switch

- Power lines (live and neutral)

- Switchgear wiring

2.3 Connection Procedure

According to the three-wire connection of the radar human sensor switch, follow the following steps to connect:

1. First, disconnect the power supply to ensure safe operation.

2. Connect the live wire (L) to the L terminal on the switch, usually a black or red terminal.

3. Connect the neutral wire (N) to the N terminal (usually a white terminal) on the switch.

4. Connect the switch wire (S) to the electrical device that needs to be controlled, usually a blue terminal.

5. Check all cables carefully to ensure that they are firmly connected and not loose.

6. After cables are connected correctly, power on the device.

2.4 Cable Connection Precautions

When performing the three-wire connection of the radar human sensor switch, the following matters need to be noted:

- Ensure wiring in the power off state to ensure safety.

- Check the quality of all wiring to ensure that the connection is strong and avoid poor contact or short circuit.

- Pay attention to the color of the wiring, usually the live line is red or black, the neutral line is white, and the switch line is blue.

- Do not reverse the live wire, neutral wire, or switch wire to avoid damage to the device or electric shock.

- Follow the wiring methods provided in the circuit diagram and equipment instructions to ensure correct connection.

Chapter Three: Application scenarios of radar human body sensing switch

3.1 Home lighting control

The radar body sensing switch can be applied to home lighting control, especially for long-term living rooms, such as living rooms, corridors and bedrooms. When someone enters the room, the radar body sensing switch can automatically sense and control the switching state of the lighting equipment, providing convenient lighting control.

3.2 Lighting control of office buildings, shopping malls, hospitals and other public places

Radar human sensor switch is also widely used in office buildings, shopping malls, hospitals and other public lighting control. By sensing the position and dynamics of the human body, the radar body sensing switch enables energy-efficient light control, automatically turning off the light when there is no human activity and turning it on when someone enters.

3.3 Applications in the security system

The application of radar human sensor switch in security system is also very important. In the intelligent security system, by connecting the radar human sensor switch with the monitoring equipment, alarm and other security equipment, the monitoring and alarm function of the entering area can be realized to improve safety.
