12Vdc PWM Dimming, Built-in Presence Sensor For Ceiling Light, Support Remote Control

• Built-in installation presence sensor
• Adopt 24GHz patented microwave antenna technology, support 4m max. installation height
• Adopt German MMW radar chip, 5 years product warranty
• Motion, minor-motion, and daylight sensor function
• Applicable for washrooms, living rooms, kitchens and other environments where motion, minor motion detection required
• Remote control available for parameter configuration

Presence: Detecting big motion signal (walking) in the detection area triggers high level output (such as control lamp on and off), and maintains output high level (i.e control light on) by detecting minor motion signals (leaning forward, leaning backward, limb swinging, shaking head, typing, playing with mobile phone and other minor motions) and abdominal and chest expansion caused by the human body's breathing vital signs.

Absence: The detection area does not detect any signal and outputs a low level (turn off the light).

Dimension diagram (unit: mm)

Functional diagram, wiring diagram

The light will be turned on 100% brightness after power on, and self test for 10s. During initialization, no external motion sensing signal will be detected. After initialization, it enters the sensing mode, during which the light remains at 100% brightness.

Sensitivity: 100% | Hold time: 30s | Daylight sensor: Disable | Stand-by period: 0s | Stand-by dim level: 20%

• Sensor should be installed by a professional electrician. Please turn off power before installing, wiring, changing the configuration.
• Microwave sensor has good penetration ability to plastic and wood. But there should be no metal accessories or metal casing, glass casing, etc. in front of or near the antenna of the microwave module, otherwise it will affect the transmitting and receiving of the microwave antenna.
• Detection area is related to mounting height, size of moving objects, moving speed of objects, working environment. And detection area in different directions will also have certain differences.
• The daylight thresholds are measured on a sunny day without shadow and in an ambient light diffuse reflection status. Different environment and climate cause different brightness values that daylight sensor measures.
• The installation spacing between product is recommended to be greater than 1.5m, and the installation spacing between product and router is recommended to be greater than 1.5m. So as not to interfere with the normal operation of the microwave.
• The installation plane of the product (for example, aluminum substrate, PCB board) needs to be a certain height different from the antenna plane of the microwave module.The spacing between antenna surrounding of microwave module and surrounding plane should be greater than 5mm to achieve the best detection effect.
• It is recommended to connect with stable DC power with lower current and ripple voltage (ripple voltage< 50mV; the minimum load current > 120mA), and to set an electrolytic capacitor filter of no less than 100uF at the VCC port of the input power supply.
• Product installation as far away as possible from large metal equipment, pipelines, air conditioning vents, exhaust vents, smoke machines and other scenes, so as to avoid equipment vibration affect the detection effect.
• The microwave module should be away from AC drive power supply, rectifier bridge, transformer, switch tube and other high-power devices to avoid high frequency signals affecting the normal operation of microwave module.
• When design product: The antenna surface of the microwave module and its nearby circuit should avoid large current flow, and it also should avoid transformers or high-frequency components nearby, the distance should be greater than 10mm.
• When wiring, the antenna side and the component side on the back of the product should not be shielded by wires or large current flow, avoid to influence the normal operation of the sensor.
• There should be no metal or glass barrier directly in front of or near the product, avoid to influence the normal operation of the sensor. Meanwhile, the height between the antenna surface and plastic should be greater than 3.2mm. The thickness of the plastic should be less than 1mm. If it is too thick, it will affect the detection effect and orientation of the microwave module.
• The distance between the antenna surface and metal plane(aluminum substrate, iron shell) is recommended greater than 0.5mm
• When the product structure, power supply mode/circuit, sensor antenna front shield changes, should notice the sensor manufacturer for confirmation, so as not to cause the product to work abnormally. Otherwise, the manufacturer does not bear any corresponding responsibility for the abnormality.
• For the new installation environment, it is recommended to test 5pcs samples before installation.
