Precautions
1. When installing the product, the antenna board is required to maintain a certain height from the metal plane. It is
recommended that the antenna board be kept at a distance of 5-12mm from the metal plane. It should not be close to or
touch the metal plane, otherwise the product may not work properly!
2. The product has a better penetration effect on plastic and wood. At the same time, avoid metal shielding in front of
the antenna, which will reflect microwaves and affect the actual sensing effect;
3. Installing glass in front of the antenna will cause electromagnetic wave reflection and penetration attenuation, which
will reduce the sensing distance of the sensor; installing ceramics in front of the antenna will also produce penetration
attenuation, the greater the thickness, the more serious the attenuation;
4. Please use a power supply with a small ripple for power supply, especially low-frequency ripples are likely to interfere
with the operation of the sensor and cause false alarms. The recommended power supply capacitor is 470 uF; it is
recommended that the power supply ripple be guaranteed within 100mV, and the ripple of 50mV is better;
5. The signal output of the sensor, the load current capacity is weak, it may not be able to directly drive the back-end
equipment.
6. When multiple sensors are used in the same site, the spacing should be greater than 0.5m. It is recommended that the
product installation spacing be greater than 1.5m. Too close installation distance may cause false alarms in individual
cycles;
7. Avoid high current circuit coverage on the antenna surface. The electromagnetic field generated by the circuit loop will
