The RCWL-0515 Microwave Radar Motion Sensor is a high-performance human detection module designed for reliable motion sensing in smart electronics, automation systems, and security applications. Unlike traditional PIR sensors, it uses microwave radar technology for stable detection through plastics, glass, and thin walls.

Perfect for DIY electronics, IoT projects, lighting automation, alarms, and smart home systems.

Key Features:

• Microwave radar detection (Doppler effect technology)
• Detects human movement reliably without line-of-sight
• Works through plastic, wood, and glass (non-metal barriers)
• High sensitivity and stable triggering
• Low power consumption for embedded systems
• Compact PCB design for easy integration

Technical Specifications:

• Operating Voltage: 4V 28V DC
• Output: Digital HIGH/LOW signal
• Detection Range: ~5m to 7m (adjustable environment dependent)
• Frequency: ~3.18 GHz microwave radar
• Delay Time: Adjustable via onboard components (depending module version)
• Trigger Type: Repeatable trigger (motion retriggerable)
• Operating Temperature: -20C to +80C

Applications:

• Smart lighting systems
• Security alarms and intrusion detection
• Automatic doors and switches
• IoT and smart home automation
• Robotics human detection systems
