HLK-LD2410B 24GHz Human Presence Radar Module (mmWave Sensor)

The HLK-LD2410B Human Presence Radar Module is a powerful 24GHz mmWave sensor designed for precise human presence detection, even when the person is stationary. Unlike traditional PIR sensors, this module detects micro-movements such as breathing and slight body motion, making it ideal for advanced automation systems.

This module is widely used in smart home systems, IoT devices, industrial automation, security systems, and energy-saving applications. Its high sensitivity and stable performance make it perfect for Bangladeshi students, engineers, and developers working on Arduino, ESP32, or Raspberry Pi projects.

The HLK-LD2410B supports serial communication (UART) and offers configurable detection range, sensitivity, and delay settings, allowing full customization based on your project needs.

If you're building a smart lighting system, automatic fan control, occupancy detection system, or AI-based automation, this radar module is one of the best choices available in Bangladesh.
