This paper prevents a wireless monitor and control system using mobile communication. This system includes the remote measurement units (RMUs), GPRS network, Internet and a server computer. The GPS, GPRS modem and advanced RISC machine (ARM) are employed to achieve the functions of RMU. The measurement data are transmitted from RMUs into the server computer via Internet protocol (IP) address. In this way, the server computer can be very far away from RMUs and it can be also flexibly assigned. The server computer can support several RMUs with flexibly assigned functions. Therefore, the measurement results can be widely spread via Internet access in real time. The proposed measurement system is applied to an example to monitor the ambient air quality. The experimental results demonstrate the performance of overall system.
