Basic Radar Sensor (LD2410)

This sensor serves as a replacement for a PIR sensor and works on the basis of microwaves and the doppler effect. Due to a difference in speed, this sensor can detect motion, this also works through almost all materials except metal

Basic Usage

This example prints the information from the LD2410 sensor to the serial monitor.

import time
import board
import busio
from ld2410 import LD2410

# Initialize UART for communication with the LD2410 sensor
uart = busio.UART(board.TX, board.RX, baudrate=256000)

# Create an instance of the LD2410 class
ld2410 = LD2410(uart)

# Read Firmware Version
ld2410.read_firmware_version()

# Wait for a moment
time.sleep(1)

def main():
    while True:
        # Update the sensor data
        ld2410.update()
        
        # Print out the parsed data
        print("Target State:", ld2410.target_state)
        print("Moving Distance:", ld2410.moving_distance, "cm")
        print("Moving Energy:", ld2410.moving_energy)
        print("Stationary Distance:", ld2410.stationary_distance, "cm")
        print("Stationary Energy:", ld2410.stationary_energy)
        print("Detection Distance:", ld2410.detection_distance, "cm")
        print("-" * 40)
        
        # Delay before the next update
        time.sleep(5)
