Smart Presence Detection Made Easy: Pdlux Launches PD-M330-K mmWave Radar Sensor

Ningbo Pdlux Electronics, a global leader in sensor technology with over 36 years of experience, has launched the PD-M330-K, a new ultra-thin 24GHz mmWave radar sensor designed to optimize smart lighting control, energy-efficient building automation, and occupancy detection.

Precision Sensing with Advanced mmWave Radar Technology

The PD-M330-K utilizes cutting-edge FMCW (Frequency-Modulated Continuous Wave) radar technology to detect both moving and stationary human presence. It captures subtle biological signals such as breathing and heartbeat, enabling accurate detection even when people are resting or asleep — making it ideal for smart homes, offices, hotels, and commercial spaces.

Key Features:

24–24.2GHz mmWave Radar Sensor

Detection Range: 1–6 meters

Ultra-Slim Form Factor: Ø80mm diameter, only 23.5mm thickness

Light Sensitivity Adjustment: 5–300LUX (day/night mode)

Time Delay Setting: 5 seconds to 3 minutes

Rated Load: 800W (resistive) / 300W (capacitive)

Low Standby Power Consumption: <0.4W

Wide Input Voltage: 100–240V AC, 50/60Hz

Indoor Use Protection: IP20

With features like automatic day/night light recognition, adjustable sensitivity, and continuous presence sensing, the PD-M330-K reduces energy waste by activating connected lighting or equipment only when human presence is detected.

Easy Integration for Smart Buildings

The PD-M330-K supports both wall and ceiling installation and is easy to configure for different environments. Its compact design and low power usage make it especially suitable for modern energy-saving projects, motion-based lighting systems, and automated building management platforms.

Ideal Use Cases:

Smart home lighting control

Office and conference room automation

Hotel corridor occupancy lighting

Restroom and hallway energy-saving systems

Green building and BMS (Building Management System) integration
