Features:Microwave sensor:This motion detector adopts a microwave sensor based on advanced technology which is safe and sensitive than infrared sensor, and the detection signal can penetrate through doors, glass panels or thin walls.High Performance:It can provides high probability of detection, low nuisance alarm and resistant to rain, dog, wind, dust, snow and temperature extremes.User-friendly extended sensing designIf someone continuously moves in the sensing area, the sensing signal will automatically extend the sensing time, and will not re-sensing after the light is extinguished.Easy to install:The wire connection method is more scientific than other products. It has 2 inlet holes and 2 outlet holes. Easy to connect and install. And pluggable terminals are used. Easy and quick to complete the installation.Wide use:It can be applied to any load, such as monitoring device, alarm equipment, LED lights, fluorescent lights, incandescent lights, exhaust fans, solenoid valves, etc.SpecificationsTypeSensor SwitchMaterial: plasticColor: WhiteQuantity: 1 pcPower supply: 220-240V ACPower Frequency: 50 or 60HZHF system: 5.8GHZ75MHz CW radar, ISMPower consumption: Approx. 0.5WInstallation sit: ceiling mountingReach:1-8m(radii.), adjustableTime setting: 8sec to 30minDetection angle:360Light control:5-2000LUXTransmission Power: Operating temperatures:-15C to 70CSize: 6.8x4.1x3.9cm or 2.67x1.61x1.53inchNet weight: 46g or 1.62ozPackages:1x Sensor Switch2x expansion pipe2x screws1x user manualNote: Pictures may be displayed differently due to different shooting angles and lights.
