Step 1

copy the code from uart_read_line_sensor_ld2410v3.h into a new file in the esphome directory, using for example Studio Code server

Step 2

Choose the ESP32 or ESP8266 code for your board

Pinout ESP32 (ESP32-S2)

esphome example code: esp-motion-kinderkamer-lucas.yaml
ESP32-S2 | LD2410
5V <-> VCC
GND <-> GND
GPIO18 <-> RX
GPIO33 <-> TX
GPIO5 <-> OUT

Pinout ESP8266 (Wemos d1 mini) Board

esphome example code: esp-motion-toilet.yaml
ESP8266 | LD2410
5V <-> VCC
GND <-> GND
TX <-> RX
RX <-> TX
D7 <-> OUT

Example including ESP32-S2 + DHT11 + Lux sensor

esphome example code: esp-motion-kinderkamer-sophie.yaml

Step 3

Make sure you change all the !secret values, or create them in your esphome secrets
Change at least the following (example)
file: esp-motion-kinderkamer-lucas.yaml

• name of the board you use
• names of the board in esphome and the motion sensor name (around line 166)

Step 4

Add to code to a new device in esphome
Once finsihed and sensor is online, you can add it in Home assistant or visit the webpage of the device.
