Model Number:Human presence sensor Origin:Mainland China Certification:CE Smart home platform:Tuya Wireless technology:ZigBee/Wifi Optional Working current:≤70mA Working temperature:-10℃~+55℃ Light sense:0-3000Lux Zigbee version:zigbee version need tuya zigbee hub to operate Working voltage:DC 5V/1A Product Size:85*27mm Radar frequency:24G Siren volume:>95dB moving detection range:0-1000cm detection angle:>90degree Note:There are two versions Wifi version doesn't need tuya zigbee hub to operate. zigbee version need TUYA Zigbee Hub to operate. It use 24G Millimeter Wave techonology.more accurate to detect the distance,time,and motion. The Millimeter Wave motion sensor can be widely used in lighing,security,home appliance.hotels,garages,buildings.transportation.LOT internet of things and other industries that need to detect human micro motion,motion and control detection distance Alarm Sensor:You can set alarm or disalarm via app. for example, it will make high sound when detect intruders.You can set the alarm time or alarm volume.and timer the schedule. Smart Human Presence Detector:the human presence sensor adopts millimeter wave radar,sensing human movement and static presence.It can detect the tiniest movement,even breathing and heatbeat. Home Security :With human presence detection,you can used to detect intruders,whether it's in your personal home,an office or retail setting or even an industrial environment. Built In 120db Alarm:Switch on and off the alarm, detect human sound and light alarm, or actively switch on and off the alarm Energy Conservation:It can not only be used to detect moving,but also non-moving people.it enables seamless background features,like the litchen light turns on once you enter the room and off once you leave. APP Remote Control:It detect micro/macro motions enables you to detect human presence within a configured distance.and get alerts in real time via app. ZigBee Hub needed:Tuya ZigBee gateway is required for this ZigBee human presence sensor,performing as the center bridge for all Tuya ZigBee smart devices with extremely stable signal and a really good necessity for whole-house intelligence.
