PIR3RF Motion Sensor — Compact, Flexible Motion Detection for Smart Homes Overview PIR3RF is a compact passive infrared motion sensor designed to detect movement up to 8 meters. Its small size and flexible mounting options make it easy to place almost anywhere. Use it to add motiontriggered automation to lighting, receive security alerts on your phone, or link it with a compatible camera via a 433 MHz RF Bridge to check who triggered the sensor. Key benefits Reliable motion detection up to 8 meters for security and automation. Small, compact design fits discreetly in tight or visible locations. Flexible aiming with a universal joint to optimize coverage without moving the sensor itself. Two trigger modes to match different use cases: frequent alerting or reduced repeat triggers. Works with devices controlled through a 433 MHz RF Bridge for broad smart device integration. Main features Detection range: up to 8 meters. Mounting options: stick directly to surfaces or mount on the included universal joint for stable positioning. Universal joint adjustment: 360degree horizontal rotation and 90degree vertical tilt for precise aiming. Two working modes: Alert mode: sensor can trigger every 5 seconds while motion stays in range for higher sensitivity to repeated movement. Normal mode: after a detection, the next trigger will occur only if no motion is detected for 1 minute, reducing repeated alerts. Gesture activation: a simple hand wave near the sensor can activate scenes or lighting when configured. Integration: requires a 433 MHz RF Bridge to communicate with compatible smart devices and cameras. Alerts: when linked to a compatible system, motion detection can generate push notifications to a mobile device and trigger connected cameras to stream or record. Installation and use Choose a mounting method that fits the location: adhesive placement for flat surfaces or use the universal joint to position the sensor where motion is otherwise hard to detect. Aim the sensor by rotating the joint to cover doorways, hallways, stairwells, or rooms. The sensor itself does not move automatically; adjust manually to the desired coverage angle. Connect via a 433 MHz RF Bridge to enable mobile alerts, camera integration, and smart scene triggers for lighting and other devices. Practical scenarios Home security: place PIR3RF near entry points. When motion is detected, receive a phone alert and open a linked camera to see who triggered the sensor. Lighting automation: install in a hallway or near a door and configure a scene so lights turn on automatically when you enter, then turn off after you leave. Nighttime convenience: mount near the bedroom or bathroom door so a simple walk triggers lowlevel lighting for safe movement at night. Compatibility and requirements Requires a 433 MHz RF Bridge to operate and to connect with other smart devices and cameras that use RF protocols. Compatible with devices and scenes that can be controlled through a 433 MHz RF Bridge. Why choose PIR3RF PIR3RF combines a small footprint with flexible installation and precise aiming, making it suitable for tight spaces and varied mounting positions. With selectable alert behavior, straightforward gesture activation, and integration through a 433 MHz RF Bridge, it adds practical motion sensing to security setups and everyday home automation without complicated installation.
