How to wire the radar human body sensor switch and installation precautions

In order to better wire and install the radar human sensor switch, we need to understand its wiring sequence and installation precautions in detail, this article will explain it one by one.

First, the basic concept of radar human body induction switch

Radar human sensor switch is a new type of sensor switch, which uses radar technology to achieve accurate detection of the human body, and can achieve accurate detection of personnel in the environment with no light or very weak light. This switch uses radar technology to emit weak electromagnetic waves, and detects the human body by detecting the electromagnetic signal reflected back by the object.

Second, the wiring sequence of the radar human body induction switch

For the wiring sequence of the radar human body sensor switch, we need to first confirm the various interface types of the switch, and determine the corresponding power and output interfaces. Generally speaking, the radar human body sensor switch will have a variety of interface types, which can be selected according to actual needs.

1. Power port

The power interface of the radar human body sensor switch is generally DC interface, which needs to use DC12V power supply. When buying a switch, we need to pay attention to the way to determine the power interface.

2. Output interface

The output interface of the radar human sensor switch generally has two types, one is normally open output, and the other is normally closed output. When selecting an output interface, select one based on site requirements.

3. Induction interface

The sensor interface of the radar human sensor switch needs to be connected to the relevant sensor module to realize the specific detection function.

Third, the wiring method of radar human body induction switch

1. Connect the power supply

Connect the power interface of the radar body sensing switch to the DC12V power supply, you can connect to the 220V AC power supply through the adapter, or directly use the 12V DC power supply.

2. Connect the output

The output interface of the radar human body sensing switch is connected to the power supply or device that needs to be controlled to realize the switch control of the power supply or device.

3. Connect sensing

The sensor interface of the radar human body sensor switch is connected to the specific sensor module, which can choose the PIR sensor module, millimeter wave sensor module or other sensor module to realize the specific detection function.

Four, radar human body induction switch installation precautions

1. Installation height

When installing the radar human sensor switch, it needs to be installed at a height of about 2.2 meters from the ground, which can ensure that it can accurately sense the movement of the human body.

2. Sensing range

The sensing range of the radar human sensor switch is generally 180 degrees, and attention should be paid to controlling the sensing range to avoid false triggering.

3. Ambient light

The radar human sensor switch has relatively low requirements for ambient light, but it should be avoided to expose it to strong light sources during installation, so as not to affect its detection results.

4. Installation position

The installation position of the radar human sensor switch should be selected in an open and unobstructed place, at least 30cm away from the obstacle.

V. Summary

Through the introduction and wiring method of the radar human body sensor switch, we can see that the wiring sequence of the equipment is very simple and clear, and only needs to be connected according to the specific interface. At the same time, we also need to pay attention to the precautions during installation to ensure that it can accurately detect the movement of the human body. I hope this article can provide some practical help to the friends who need to install the radar human sensor switch. If you have more questions or need more in-depth understanding, it is recommended to consult a professional technician.
