This is a hi-precision digital microwave sensor whose detection range is 360°and working frequency is 5.8GHz. It is based on

doppler principle which integrates the emitting and receiving. It adopts MCU (Micro Control Unit) that greatly increases its

precision and decreases its fault rate. It’s delicate in appearance and compact in structure. It can be independently connected to

the loads or easily installed inside the lightings with lampshade made of glass or plastic. It is widely applied in the passageway,

washroom, elevator, household or other public areas for security protection or energy saving. It applies for several technical

patents and is the perfect choice for your intelligent living.

It uses the MCU to accurately calculate the switch information, and accurately controls the relay to be turned on at the zero point

of the sine wave, so that each load is turned on. At the zero point of the sine wave, the inrush current problem caused by the

conventional control mode when the sine wave high voltage is turned on is avoided, especially the large current damage relay

generated by the large-capacity capacitor under the impact of the high voltage under the load.Due to the diversification of current

electrical loads, especially LED lamps, energy-saving lamps, and fluorescent lamps all have capacitors with different

capacitances. This is a disaster for relays. Sometimes a 50W LED lamp can generate surge currents of 80 to 120A. The 10A

ordinary relay can only withstand 3 times of the inrush current, and it is likely that the relay will be broken in a few days or several

times. This is why the conventional sensor on the market has a short life and a small load current.

In order to overcome this problem, this product adopts advanced digital precision calculation to turn on the load when the sine

wave is at zero potential, thus solving the load surge current problem, greatly enhancing the load capacity and prolonging the

service life of the product. The latest control method of mass production sensor technology can easily control any load. It is a

medium and high-end product. Although the cost is increased compared with the conventional version, the reliability and life of

the product are greatly increased. This product is equal to choosing peace of mind, and choosing safety.
