LD1020 Motion Sensor Module | Ultra-Low-Power Radar Presence Detector for Smart Home & Lighting | Adjustable Range & Ambient Light Detection | Ideal for Concealed Installation

The LD2450 is a highly capable 24 GHz millimeter-wave radar sensor designed for precise motion, position, and speed detection. It can detect even the smallest micro-movements, track up to three targets simultaneously, and operates with exceptional reliability—unaffected by light conditions, temperature, or humidity. Perfect for smart home projects, IoT devices, automation systems, and research.

Product Features

Precise Real-Time Position Detection
The sensor measures the distance, angular position, and speed of moving people or objects using intelligent FMCW signal processing. Up to three targets can be detected and tracked at the same time.

Long Detection Range & Wide Field of View
 • Detection range: up to 6 m
 • Field of view: ±60°
This makes the LD2450 ideal for rooms, hallways, entrances, offices, and retail environments.

High Environmental Robustness
Light levels, shadows, temperature fluctuations, and humidity do not affect the sensor’s performance—ensuring reliable detection in almost any environment.

Easy Integration into Electronics & IoT Projects
The UART interface (256000 baud, 3.3 V IO level) allows fast and simple integration into microcontroller platforms like ESP32, Raspberry Pi, STM32, and many others.

The sensor outputs:

• X-coordinate
• Y-coordinate
• Speed
• Distance (up to 10 updates per second)

Compact Design – Ideal for Discreet Integration
Measuring only 15 mm × 44 mm, the module fits easily into existing products such as smart lights, HVAC systems, monitors, or security solutions.
