LIFEBEING SENSOR MSA043D 485 Version: A0
page 2of 12
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.
