The 24GHz Radar Human Presence Detection Controller is an advanced sensing solution designed for accurate and reliable occupancy detection. Unlike traditional motion sensors, this controller uses high-frequency radar technology to detect even the slightest human presence, making it ideal for smart lighting, energy-saving systems, and automation applications.

Key Features
• Human Presence Detection (High Sensitivity)
Utilizing 24GHz radar technology, the controller can detect micro-movements such as breathing or slight body shifts. This ensures that lights or systems remain active even when a person is sitting still, providing a more comfortable and intelligent user experience.
• Wide Detection Capability
The sensor supports a detection range of up to 3–4 meters, making it suitable for small to medium indoor spaces.
• Penetration Ability
The radar signal can penetrate thin gypsum boards, walls, or non-metal materials up to approximately 6 cm thick, allowing for flexible and concealed installation.
• Ambient Light Sensor Integration
Equipped with a built-in light sensor, the device only operates when ambient light is below 30 lux, ensuring energy efficiency by preventing activation in bright environments.

Important Notes & Installation Guidelines
• Detection Range
Maximum effective detection distance is 3–4 meters. Performance may vary depending on the environment.
• Material Penetration Limitations
• Can penetrate thin non-metal materials (e.g., gypsum board, plastic, wood up to ~6 cm)
• Cannot penetrate metal
• Do not install inside metal lamp housings, as this will block the signal
• Driver Interference
If the lighting fixture includes a driver (power supply), maintain a distance of 15–20 cm between the radar module and the driver to avoid signal interference.
• Sensitivity to Micro-Movements
The sensor is highly sensitive and may be triggered by slight movements such as:
• Fans
• Curtains moving due to wind
Therefore, it is not recommended for outdoor or windy environments.
• Light Sensor Behavior
• The sensor only operates when ambient light is below 30 lux
• In bright environments, the sensor remains inactive
• If daytime operation is required, the light sensor can be covered with black tape to disable this function
• Delay Off Function
After no micro-movement is detected, the system will automatically turn off after approximately 20 seconds
