Feature: Automatic induction: It is a piro sensor automatic product. It can detect the motion of people, when people enter the detecting area, it will light on; when people leave, it will light off with 15s delay. It will turn on only when it is dark and when motion is detected. Autoon within 10 feet, autooff after 20 seconds of no motion detected helps prolong battery life.


Sensor, Occupancy Wireless SPIRWL1 PIRO Sensor

The PIRO sensor has a very large field of view and by combining temperature sensing with motion, the sensor eliminates false activation from light, sunlight, moving objects such as curtains, etc. The angle of the sensor can also be adjusted as to keep small animals out of the site of the sensor. The life of the battery should last approx. 2 years.
