Signal Detection Description

This millimeter-wave radar sensor detects human body movement, micro-movement, and presence signals, and realizes the detection of human body presence(human-existing/no-human) in a non-sleeping state. The following is a description of movement, micro-motion, and presence signals:

Majormovement: detect the human significant moving (walking) in the detection area.
Minor movement: detect the human slight moving in the detection area, such as leaning forward, leaning forwarder and back, swinging limbs, shaking head, typing, playing with mobile phones and so on.
Micromovement: detect human abdominal and thoracic expansion behaviors caused by breathing, but not detect moving signal and minor moving signal.

Wiring suggestions

Wiring Diagram & Recommendations

Wiring recommendations:

KNX bus wiring suggestion hand in hand to the end, star or tree wiring is not recommended to ensure the stability of signal tranmission.
KNX bus wiring wire recommends KNX standard EIB shielded wire or Category 6 network cable, the length of the bus wiring is recommended not to exceed 400 meters, and the number of sensor connected to a bus is recommended to not exceed 12.
The number of sensors connected to a bus needs to fully consider the current load capacity of the power supply: that is the sum of the currents of all KNX devices (including sensors) shall not be greater than the load current of the KNX power supply.
