Human Presence Sensor – 24GHz mmWave Radar Switch (SCH-LD2410C)

Detects human presence in moving and static states using advanced 24GHz mmWave radar technology. Unlike PIR sensors, it can sense micro-motions such as breathing and sitting. Integrated switch design allows direct control of lights or fans without any external con

Human Presence Sensor – 24GHz mmWave Radar Switch

SCH-LD2410C | Smart Occupancy Detection

The SCH-LD2410C Human Presence Sensor is a next-generation 24GHz mmWave radar-based presence detection switch designed to detect humans even when completely still. It provides accurate, real-time occupancy detection for modern smart lighting and automation systems.

This sensor integrates the radar module and switching circuit into a single compact unit, allowing it to directly switch AC loads such as lights or fans — eliminating the need for microcontrollers, relays, or smart hubs.

HOW IT WORKS

Using 24GHz FMCW radar technology, the sensor continuously analyzes reflections from the human body. Even the smallest movements like breathing or posture changes are detected, ensuring the system knows when a space is truly occupied.

Once no human presence is detected, the sensor turns the load OFF after an adjustable delay time, helping reduce energy waste.
