Based on the ARM microcontroller technology, an effective method to monitor smart home remotely is presented in this paper. In practical applications, to achieve remote data communications monitoring operation, this approach uses Web browser as operating interface. The nRF24L01 Radio Frequency modules which can involve 32 bytes payload, setup the wireless data communication platform for smart home terminal device. By the definition of data frame format, the approach finishes the design of the wireless communication protocols and unifies the application interface of basic devices, which increases the flexibility of smart home development. The remote monitoring system play an important role on monitoring house environment and other distributed sub-system, enrich and extend the operation for house intelligentize.
