How to connect the radar human body induction switch

Radar human sensor switch is a kind of intelligent switch equipment, which is widely used in home automation control. In the installation and use of the equipment, it is very important to master the proper wiring method. This article will introduce the wiring method of radar human sensor switch in detail, to help you better complete the installation and use.

First, the principle of radar human induction switch

Radar human sensor switch uses radar technology. As we all know, as long as the object exists, it will reflect back the signal. Radar human sensor switch uses this principle to realize the monitoring of the surrounding human signals. The device can sense signals reflected back from the human body to link other devices, so as to control the switch of related devices.

2. Wiring method of radar human body induction switch

1. Wiring diagram of radar human body induction switch

Among them, 1 and 2 points are external control lines. If external control is needed, wiring can be added. 3, 4 and 5 are used as power cables for the equipment, which shall be connected according to the positive and negative terminals.

2. Connection method

First, prepare the tools and materials required: radar body sensing switch, terminal, wire, etc. The specific steps are as follows:

a. Connect the power cable. Connect the red power cable to the positive terminal and the black power cable to the negative terminal.

b. Connect the control cable. Connect the 1 and 2 points to other devices or controllers. It is important to note that the polarity of the control line should be consistent with that of other devices or controllers.

c. Set the radar human sensor switch. There are some rotary switches and distance switches on the switch, which can be set according to specific needs. When setting the distance, you can first place the switch to the position of the required detection distance by hand, and then fine-tune it by adjusting the distance adjustment switch.

3. Precautions

a. You are advised to select wires and connectors with proper specifications to ensure device security and stability.

b. Pay attention to the voltage and current in the circuit to ensure that there is no short circuit or overload.

c. In use, dust and other impurities on the surface of the equipment should be cleaned frequently to ensure the normal interaction between the equipment and the outside world.

Four, radar human body induction switch installation notes

1. Installation height:

Lamps and lanterns should have a certain distance from the ground, generally not less than 2.2 meters, can also be adjusted according to the need. At the same time, during installation, it is necessary to ensure that the distance between the radar human body induction switch and the lamp is moderate, so as to avoid the inaccuracy of detection.

2. Installation position:

Attention should also be paid to the installation position of the radar human sensor switch, which should be around the need to monitor human signals, but at the same time, it should not be installed in too high a position, so as not to affect the use of the equipment.

3. Ambient temperature:

The ambient temperature of the radar human sensor switch should be between -20 degrees and +50 degrees. Too low or too high will affect the detection accuracy and service life of the equipment.

4. Light Lighting:

Radar human sensor switch is not affected by light and light, but during installation, attention should be paid to avoid the light shining directly on the equipment and causing induction misjudgment.

Five, the advantages and disadvantages of radar human induction switch

1. Advantages:

Radar human sensor switch has high detection accuracy, wide monitoring range, and has the advantages of power saving and energy saving, long service life.

2. Disadvantages:

Radar human sensor switch has high requirements on temperature, humidity and other environmental factors, so it is not suitable for use in harsh environment, and its price is relatively high.

Vi. Summary

Radar human sensor switch is a kind of intelligent and high-precision home automation control equipment, which is of great significance for improving the quality of life, promoting energy saving and emission reduction. In this paper, the principle of the equipment, wiring methods, precautions, advantages and disadvantages are introduced in detail, if there are shortcomings, please forgive me!
