In view of remote-monitoring problem for indoor environmental parameters, a remote wireless-monitoring system based on ZigBee technology and mobile phone is proposed, which is used to realize the real-time data exchange. The sensor nodes collect the temperature, humidity, light intensity and smoke concentration, and transmit the data to the central coordinator by the ZigBee wireless network. The coordinator is connected with the WIFI module through the serial port, by which, the data is sent to the Internet. In addition, an Android mobile phone software is designed for the data acquisition, and issues instructions for adjusting parameters to complete the remote wireless monitoring task. As the test results show, the mobile phone is able to acquire and control the real-time environmental parameters in any place where the network is available. At the same time, the performance of nodes work stably and meet the need of long-term monitoring.
