Summary

This product is an advanced digitally controlled infrared pyroelectric intelligent sensor product. 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, 

choosing peace of mind, and choosing safety.

This product has a switching power supply version and a capacitor step-down version. The switching power supply 

version has a working voltage of up to 100V-277V and a standby power consumption of <0.5W. In principle, the 

capacitive step-down version can only have a single voltage, and the standby power consumption is >0.7W. You should 

consider it when choosing a product.

LUX adjustment:

LUX refers to the illuminance of the environment. Adjusting the LUX adjustment knob allows you to choose which 

illuminance you want to get the sensor into the induction. Choose the habit that suits you.

Some of the choices in the 20LUX solution are to be illuminated. Some choose 50LUX ambient illumination to be 

inductive lighting, and some choose to be inductive lighting at any time, as long as the LUX adjustment knob is 

adjusted to the maximum.

Time adjustment:

The time adjustment knob is used to adjust the time after the sensor senses the light, and the user can reasonably 

select the delay time after the induction.
