1、Status indications can sense effective LED fault for easy installation and failure analysis. 2、With special temperature compensation chip, can reduce the sensing distance affected by temperature. The induction angle is 110 degrees, very convenient. 3、Adopts the most advanced imported internal sensor and circuit. Light will start automatically when pedestrians into the sensing range. Light will delay and shut down automatically when they leave. 4、This photosensitive control design, is friendly, safer and energy-saving when in use. The induction distance is abput 5-10m/16.4-32.8ft and light control range is 5Lux -500Lux ± 20%. 5、With the function of random delay, there is a delay to work for a certain period of time if no one is there. Can adjust the delay time freely within the appropriate range of 30-350 Secs ± 30%. 6、Can achieve automatic control based on infrared technology. The switch automatically turns on when the special sensor detects the change of the infrared spectrum of the human body. The switch delays will be automatically turned off after people leave here.
