The solution adopts the 5.8G/10G low-power microwave radar module series to wake up the door lock according to the set sensing distance (such as about 1 meter), and perform functions such as face recognition to open the door, improving user experience and taking into account low power consumption.This solution has many good features such as no need to open holes and grooves to destroy the appearance of the lock structure, the industry’s lowest power consumption of 29uA,various module size to adapt N styles of structure of locks,and it can support stay auxiliary detection and other algorithms.
