Radar body sensor How to control lights: A complete operating guide

Radar body sensor is a new kind of sensor, which can monitor and sense human movement through radar wave, so as to achieve accurate intelligent control. In today's era of changing science and technology, more and more home products begin to embrace the trend of intelligence and convenience, and radar body sensor as a core device of smart home, has begun to obtain a wide range of applications in all walks of life. This article will focus on how to control the lights with radar body sensors to build a smarter, more convenient home environment for you.

I. Principle of radar human body sensor technology

Radar body sensor uses radar technology to detect the human body with high-frequency electromagnetic waves. By analyzing the changes of electromagnetic wave signals reflected back by the human body, it can monitor the trajectory, speed, direction and other information of the human body. Compared with infrared sensors, radar body sensors can penetrate objects without interference, so it is more sensitive, safe and practical.

Two, control principle

Radar human sensor realizes the control of light by receiving signals around human body. The control principle can be divided into two ways:

1. Determine the static or moving state of the human body

Sensors detect and process surrounding signals to determine whether the body is stationary. If the body is judged to be static, the light can be controlled by the switch. If the human body is in motion, that is, the "activity" function of the sensor is activated, then the light can be switched on and off.

2. Determine the distance between human bodies

Another control is to adjust the brightness and color of the light depending on the distance between the body and the sensor. When the human body is near the sensor, the brightness of the light gradually becomes brighter. When the human body moved away from the sensor, the brightness of the light dimmed.

Three, how to install the radar body sensor

Considering the working principle and safety of radar human body sensor, we will introduce the correct installation steps of radar human body sensor in detail.

1. Select an appropriate installation position

First of all, we need to determine the installation position. Generally speaking, due to the wide range of work of the radar human body sensor, we can monitor a wide range of space, so we can choose the location of the TV cabinet, bedside table, hall and so on to install.

2. Determine the height of the installation position

The height of the installation position must be appropriate. Too high a height may affect the sensor's induction range and sensitivity, while too low a height is easy to be blocked by people and objects and the illusion of the distance and position of the light. It is recommended that the installation height be about 2-2.5 meters.

3. Secure the sensor

Use a drill to secure the sensor to the installation position. You can use wall screws or magnetic suction bases to secure the sensor.

4. Check the power connection

After the installation, check whether the sensor is properly connected to the power supply. It is important to note that the power supply of the sensor must be connected to the correct voltage, otherwise it may cause unnecessary impact on the human body and equipment.

Four, how to achieve lighting control

When the radar body sensor is installed, the following steps are required to achieve lighting control.

1. Select the control mode

Based on the two control modes mentioned earlier, you need to select the corresponding control mode. If you choose the first mode, you need to set the sensor to the "rest" mode. If you choose the second mode, you need to set the sensor to "Distance Control" mode.

2. Connect lights

When connecting the light to the output port of the sensor controller, it is necessary to determine whether the working voltage of the light matches the voltage of the output port of the controller.

3. Set sensor parameters

It is necessary to realize the lighting control through the parameter configuration of the sensor, including the control mode, delay time and sensitivity.

4. Debug and test

On the basis of pre-set control mode and parameters, demonstration tests should be carried out. During the testing process, attention should be paid to the influence of the environment, such as whether the ambient sound is too loud, whether there are occlusive objects and so on.

V. Summary

Radar human body sensor is a sensor device with advanced technology, intelligence and convenience, which can bring more convenience and intelligence to our daily life. With the above steps, you can easily install radar body sensors in your home devices and achieve intelligent control of the lights. At the same time, this paper also reminds the majority of consumers, choose the appropriate sensor model, follow the correct installation and use method, in order to play the use of the sensor benefits.
