The Remote Wireless Monitor System presented here is based on the PTR2000 Remote Wireless Model. It is a microminiature, low power, high speed, and highly sensitive wireless dispatcher with two channels and the capability to satisfy the need for many channels operating at the same time. The system can connect to a single chip directly and perform node-to-node data collection. Remote Wireless Monitors are widely applicable with uses spanning: industry control, industry data collection, remote control, remote measurement, wireless data exchange, gate ban systems, radio transceivers, mini wireless data terminals, wireless remote control systems, weather monitors, and robot control. The Remote Wireless Monitor System presented can be conceptually divided into several components: the PTR2000 Remote Wireless Model, the LabVIEW software system, and the AT89S51 MCU. This system realizes wireless communication through a four-step operation. The signal is first detected by the ADC0809. Following signal detection, the data is simultaneously forwarded to the LED display board and the AT89S51 MCU. The AT89S51 MCU acts as a control unit, passing the data to PTR2000, which transmits the signal to the recei
