Intelligent multi-channel wireless data acquisition gateway

摘要

The present invention is an intelligent gateway which can receive multiple sensor data using sub-1G Hz frequency, analyze data, and transmit processed data to a database server. The intelligent gateway can receive data from up to 100 sensors using sub-1G Hz (433, 868 or 915 MHz) wireless frequency. The received data can be analyzed and the gateway can determine when to transmit data, and which packaged data to transmit to the database server. The intelligent gateway can also receive feedback and instructions from the database server. The process data can be transmitted to the database server with different protocols like WIFI, Ethernet and RS485. The intelligent gateway can also include multiple sensors including temperature and humidity sensors, pressure sensors, air speed sensors and a particulate matter sensor for detecting particulates of less than 2.5 micro meters (PM2.5). These sensors are collect additional indoor environmental quality parameters.
