Product Specs

7
1.The installation process requires to keep a certain height between the antenna plate from the
metal plane, can not cling to or touch the metal plane, otherwise the product may not work
properly!
2.Avoid installing together with metal accessories or shell,when install microwave motion
sensor,metal will absorb or block microwave and affect normal detection.Therefore, this product
should not be installed in the metal shell for use. However, such as plastic, ceramic, and Woody
earth obstacles, the penetration effect is relatively good;
3.Please use power supply circuit with tiny ripple current, especially the low frequency ripple,
which disturb the sensor's work easily.
4.The output current of the sensor is very weak, If driver too large current easy to cause false
alarm. Better drive the load by isolation drive, and can also use MCU to read the output state.
5.The recommended installation space of sensors is more than 1.5m,and the installation distance
is too close may cause individual cycle misstatement;
6.Avoid large current circuit cover of the antenna surface, which may lead to interference.
Additional Remarks
Warning: IFI/IFQ output signal is sensitive to ESD(electrostatic damage),if exposure to high
electrostatic or power source areas may cause irreversible damage to the radar module
Recommendation: It is recommended to use a qualified DC voltage stabilizing power supply.That is,
DC voltage, current, and ripple coefficient that are all up to the standard, otherwise it will affect the
stability of this product and may cause some anomalies, such as: false alarm, no detection,
circulation, self-start, etc.
