RCWL0515 Microwave Radar Motion Sensor Module 2pc Overview A compact microwave motion detection module that uses radar technology to sense human movement. The RCWL0515 delivers reliable, longrange detection with wide coverage and low power consumption. Ideal for lighting control, security sensors, and automation projects. Key benefits True nondeadangle detection: planar antenna emits microwave signals and receives reflected echoes, providing wide coverage and fewer blind spots than typical infrared sensors. Greater range and penetration: typical sensing distance up to 12 meters and can detect through glass and thin veneers. Penetration through walls varies with supply voltage and installation conditions. Low power, wide voltage range: works from 4 to 28 volts with a typical operating current of 4 mA, suitable for battery or DCpowered applications. Adjustable behavior: repeated triggering time is adjustable to tune response for different environments and reduce false triggers. Small and easy to integrate: compact PCB size fits into tight spaces and can be added to existing control circuits.
