雪花飘。是优点也是缺点。

只适合侧装，没法检测静止

如果玄关和客厅相连，可以用2450这种。设定玄关和客厅的XY区域，可以实现人来灯亮，人走灯灭。


定论：模块都是好模块，就看你会不会用

To create your own presence sensor based on the Hi-Link LD2450, you are going to need a couple of things.

First, you need to decide on the LD2450 model and form factor, which will impact how you approach attaching the sensor to an ESP32 Board.

you have all the components and tools ready, you can start to assemble this DIY presence sensor.

you need to do is connect a few wires from the ESP32 board to the Hi-Link LD2450 presence sensor .

code it in ESPHome


调参用海陵科的app就行

Step 1: Build a control circuit.
Connect the 5V power supply and the UART from the microcontroller to the sensor. Be careful, the color of the wires may differ.

需要LD2450与esp32相连，后面通过ESPhome接入ha

ESP32    LD2450
5V  <->  VCC
GND  <->  GND
TX  <->  RX
RX  <->  TX

Step 2: Configure your ESPHome device with YAML
See the file example_ld2450.yaml
