LD2410C 24GHz Human Presence Radar Sensor

LD2410C 24GHz Human Presence Radar Sensor is a high-sensitivity mmWave radar module designed to detect human presence, motion, and micro-movement (like breathing) through advanced 24GHz radar sensing. Unlike PIR sensors, the LD2410C can detect stationary people and provides more reliable occupancy sensing in smart environments.

Key Features

• 24GHz mmWave radar for presence + motion detection

• Detects moving and stationary human presence (micro-motion capable)

• Works in darkness and is less affected by temperature than PIR sensors

• Adjustable detection parameters (distance/sensitivity) via configuration tools (model-dependent)

• Stable performance for smart home occupancy and automation triggers

• Compact module size for easy integration into devices and enclosures

Applications

• Smart home occupancy sensors (lights, AC, automation scenes)

• Smart switches, wall sensors, and room presence detectors

• Energy-saving systems in offices and meeting rooms

• Security systems and human detection alarms

• Smart hotel rooms and building automation

Used In

• Home Assistant / ESPHome presence projects (via MCU like ESP32/ESP8266)

• Smart lighting controllers and motion + occupancy nodes

• IoT gateways and embedded automation products

Package Includes

• 1× LD2410C 24GHz Human Presence Radar Sensor Module
