A remote indoor environment monitoring system based on wireless sensor networks（ WSNs） is designed to deal with problems in current indoor environment monitoring system

such as complicated routing

high cost

high power consumption. Environmental factors monitoring is achieved by developing wireless sensor node which chooses CC2530 as the core. Gateway node is structured based on Cortex—A7 MT7623 A microprocessor

and Linux operating system

which has functions of high-performance router and Zig Bee coordinator. The data collected by sensor node is sent to remote server

and the environment quality grade is evaluated through two-level data fusion. Preliminary experiments show that the system which has advantages of low power consumption

flexible networking and strong expandability

which meet the application requirements of indoor environment monitoring excellently.
