PIR motion sensor combining infrared and microwave detection for reliable, sensitive motion monitoring in homes and small properties. Key benefits sensitivity detection: Dual infrared and microwave sensing detects movement at 812 meters, ensuring prompt detection and reducing missed incidents. Improved accuracy: Two independent sensing methods crosscheck motion events to minimize false alarms and provide consistent monitoring for doors, windows, and restricted areas. Pet immunity: The sensor distinguishes human activity from pets up to 30 kg, preventing unnecessary alerts while keeping occupants and animals comfortable. Durable, compact design: Constructed from ABS, the wired wallmounted sensor measures 125 x 42 x 71 mm and performs reliably across a wide range of conditions. How this solves common problems Reduces false alarms caused by pets and small animals, so users only receive meaningful alerts. Combines two sensing technologies to avoid missed detections that can occur with singletechnology sensors. Compact and robust housing adapts to typical household environments without drawing attention. Practical applications Entryway and door monitoring: Install above doors to detect intrusions or unexpected movement near main entrances. Window and perimeter protection: Mount near groundlevel windows or basement access points to add another layer of detection. Petfriendly living areas: Use in rooms where mediumsized pets are present to maintain security without frequent false alarms. Technical highlights Detection range: 812 meters Sensing: Passive infrared plus microwave Pet immunity: Up to 30 kg Size: 125 x 42 x 71 mm Material: ABS Power: Wired sensor Operating conditions: 30 degrees C to 75 degrees C; 5 percent to 95 percent relative humidity Mounting: Wallmounted This sensor provides a practical, reliable option for improving home security coverage while reducing nuisance alarms and accommodating households with pets.
