1. Features
This is a RS485 protocol sensor of independently flush mounting(compatible with 86 type box). The sensor,
controlling and exchanging data through RS485 protocol, has functions of big motion, minor motion, breathing
detecting+light sensing and so on. Adopting 5.8GHz RS, high gain low impedance technology, MSA043D is
achieving presence detecting as its big advantage. Besides, MSA043D can independently access RS485 system
as a unit of data collecting for its RS485 communication standard.

LIFEBEING SENSOR
1) Adopting living body detecting technology that it can accurately
detect big motion, minor motion, breathing detecting to achieve
true presence detecting.
2) Intelligent daylight sensing and recognizing.
3) Collecting and transmitting data through RS485 port, it is
suitable for smart building, smart hotel, home lighting and other
relevant area of intelligently controlling.
