COOS A1 is a software and hardware integrated system for sensor data collection and processing. This system collects state data of local system through rich data collecting interfaces, transmit them to COOS data cloud or edge system via IoT protocols and communication protocols, then performs a series of processing including data formatting, data cleaning, valuable information extraction, secure data storage, etc., realize conversion from raw data to valuable information, achieving full service from IoT device side to COOS data cloud ecology.
