Heath/Zenith HZ-5316-WH VA-HP008 DLX WHT Motion Sensor, White

all hastiness motion lights have a motion sensor the sensor is the primary component of the light fixture and contains all of the control functions and motion sensors that operate the light fixture let's take a closer look at the sensor across the front of the sensor you will notice the sensor lens the lens not only protects the motion sensor from the weather but especially designed to create zones to help promotion sensor see movement heat Sina sensors are available in a variety of detection angles to work in many different applications 110 degrees 150 degrees 180 degrees 240 degrees and 270 degrees the motion sensors do not actually see physical movement but rather detect the movement of temperature differences across the zones created by the lens as a result the sensor is more sensitive to the movement across the front of it than it is to moving it toward it because the sensor detect
