LD2410 1.1.1

A python interface for the HiLink LD2410 presence detection module

LD2410 Interface for Python

More documentation coming soon. In the meantime, you can read example.py to figure out how to use the module

A python interface to control and get data from a Hi-Link LD2410 module over a serial connection

How to install

Run pip install LD2410 using your package manager of choice

Usage Instructions

An example of how to get full data from the module

from  LD2410  import *
import time

radar = LD2410(port="/dev/ttyUSB0") # Replace <port> with your serial port. e.g "COM3" or "/dev/ttyS0" etc. 

radar.enable_engineering_mode() # Enable engineering mode to get full data

# You must call call start() before getting data, or you get nothing
radar.start() # Start the radar module

# Get 60 data frames
for _ in range(60):
	print(radar.get_data())
	time.sleep(1) # Radar module will keep running in the background, but we only retrieve the latest data every 1 second

radar.stop()

How to get the data

Use radar.get_data()

It returns the following:

In standard mode: ([Detection Type, Movement Gate Detection Dist, Movement Gate Energy, Static Gate Detection Dist, Static Gate Energy, Detection Dist], None, None)

	Detection Type
0	No Target
1	Moving Target
2	Static Target
3	Moving and Static Targets

Movement Gate Detection Dist: The distance of the detected moving target from the sensor Movement Gate Energy: The "energy" level of the detected moving target Static Gate Detection Dist: The distance of the detected static target from the sensor Static Gate Energy: The "energy" level of the detected static target

What is a gate? * A Gate is a region of N * 75 to (N + 1 * 75) cm region from the sensor. For example, Gate 2 refers to a region between 1.5m and 2.25m away from the sensor

In engineering mode: ([Same as above], [Moving gate 0 energy...Moving Gate 8 Energy], [Static gate 0 energy...Static Gate 8 Energy])

Moving gate 0 energy...Moving Gate 8 Energy: Get the energy levels of each gate returned as a list of integers

Static gate 0 energy...Static Gate 8 Energy: Get the energy levels of each gate returned as a list of integers

1. Expand on how to set params

2. Expand on how to change sensitivities
