The no built-in LED variant of the series, the ESS-100 can be integrated with external lighting, as a sensor that turns them on when it detects the presence of an occupant. The ESS-100 automatically switches lights on or off, using Pa-PIR passive infrared sensor technology; which detects motion as well as body temperature, ensuring spaces are illuminated only when they are occupied. This easy to install Motion Sensor is ideal for residential, commercial, and office spaces; allowing you to save up to 60% of your lighting-related energy consumption. Now you can enhance both the sustainability and occupant experience of your built spaces, at the same time. Smart lighting was never so easy.
