Choice of dynamic sensors need to pay attention to what?

Note: the dynamic sensor selection can be selected using the ultrasonic sensor in the shield area and furniture separate areas; when using the passive infrared sensor (PIR); the closed area is divided into regions in the large area using different sensor control and management of lighting system using dual sensor technology in a small amount of activity regional; 4 for vibration of place, to install the sensor on the stability of the surface, the position sensor is installed above or near the main activities in the region; the mask lens to correct alignment sensor to make the control area; the use of other control methods (such as control, the predetermined time integrated sensor and lighting) what happens on the new equipment and will be the education of residents.
