Properties

868 Mhz, 920 MHz, Plug & Play, S8, S9

PIR Sensor is a compact wireless motion detector designed to identify movement within protected indoor areas. Using low-power wireless networking technology and digital signal processing, the sensor reliably detects people moving within its coverage area and sends an alarm signal to the connected gateway.

With a detection distance of up to 10 meters, a 120° detection angle, adjustable sensitivity, and two-way wireless communication, PIR Sensor is suitable for residential, commercial, and light industrial security applications. Available in 868 MHz and 920 MHz versions, it features low-power operation, encrypted wireless communication, and anti-interference technology to help ensure stable and dependable performance.

Detailed Sensor Capabilities

Core Features

Reliable PIR Motion Detection: Detects human movement within a protected area using passive infrared sensing technology.
Up to 10 m Detection Range: Provides effective indoor motion detection coverage for rooms, corridors, and protected areas.
120° Detection Angle: Wide-angle detection helps cover more space with fewer devices.
868 MHz / 920 MHz Wireless Communication: Available in 868 MHz and 920 MHz versions for wireless communication with a compatible gateway.
Two-Way Communication: Supports reliable interaction between the detector and gateway.
Encrypted Wireless Signal: Uses AES128 advanced encryption and Rolling Code technology for secure communication.
Anti-Interference Performance: FHSS automatic frequency hopping improves resistance to external radio interference.
Adjustable Sensitivity: Supports different sensitivity settings to adapt to normal or more challenging environments.
Selectable Working Modes: Includes saving mode and normal mode for different alarm reporting needs.
Low Battery Prompt: Notifies when the battery level is low.
Compact Indoor Design: Suitable for discreet wall-mounted installation.

Typical Application

Residential Security: Motion detection for rooms, hallways, entrances, and bedrooms.
Commercial Spaces: Protection for offices, storage rooms, corridors, and restricted areas.
Gateway-Based Alarm Systems: Designed to work as a wireless accessory connected to a compatible smart gateway.
Indoor Perimeter Monitoring: Helps detect movement inside protected zones and trigger alarm reporting.
Flexible Installation: Can be installed using double-sided tape or screws depending on the mounting surface.
