About LED Motion Sensor Light Switch, Occupancy Sensor

Why Microwave Motion Sensor, not PIR? PIR sensor activated by infrared, heat and light. Sensitivity is lower when background temp. Reaches 37℃. Vulnerable to dust and smoke. It also can not pass through plastic, glass cove. Lens gets aging, and as time goes on, the reaction will be more and more sluggish. Microwave motion sensor activated by motion and speed, no lens, do not worry about lens aging or dust and smoke detection because it can be detected through plastic, glass and thin non-metal materials, always functioning regardless of the background temp. Smart sensor automatic turn on lamp only on your need 1.Ambient lux level is above preset daylight threshold, the lamp does not switch on. 2.Ambient lux level is below preset daylight threshold, When nobody or no objects move, the lamp does not switch on When somebody or others move, the lamp will turn on, if there is no more movement , the light turns off automatically after hold-time preset.
