Infrared Ceiling Sensor

Infrared Ceiling Sensor

Type: AS-936


Related: PIR Sensor


AS-936 infrared ceiling sensor combines advanced optical design and electronic design, it’s intelligent, with ultra-thin design, microprocessor control, true temperature compensation and anti-electromagnetic technology. And using proprietary Fresnel optical lenses, it is enhanced anti-white light interference ability, basically eliminate the phenomenon of false positives.
