Overview

Product Overview

The HLK-2410B is a human presence radar motion detection module designed to sense occupancy and movement more reliably than simple PIR sensors, making it a strong choice for smart lighting, home automation, security alarms, interactive kiosks, and robotics projects. As a compact radar-based presence sensor, it helps systems detect when a person is nearby, remains in an area, or is moving, enabling responsive automation and reduced false triggering in indoor environments. Ideal for prototyping and embedded builds, this pre-soldered module is well suited to custom controllers and maker platforms including Arduino, ESP32, and Raspberry Pi.

Questions & answers

Frequently asked questions

Yes. This module is described as well suited to Arduino, ESP32, Raspberry Pi, and custom controllers. The host board still needs compatible wiring and project software to read and use the presence or motion output.
Yes. This ShillehTek version is pre-soldered, so the header pins are already attached for jumper-wire or breadboard-style prototyping. You still need to connect it to a controller and configure your project software.
Before connecting it, verify the module pinout, required supply, and signal logic compatibility for your controller. The listing does not specify exact electrical ratings, so follow the module documentation and avoid assuming PIR sensor wiring.
Yes. It is designed for human presence and motion detection, which fits smart lighting, home automation, security alarms, kiosks, and robotics. Radar-based sensing can detect occupancy more reliably than a simple PIR in indoor projects.
Radar presence sensors can respond to nearby people, movement, placement, and configuration, so test the module in its final mounting location. If triggers are unwanted, review wiring, power stability, and controller code before replacing hardware.
