The Remote monitor is based around a MCS-51 micro controller with a 433MHz radio receiver. The Remote modules each contain a micro processor with a radio transmitter. Each time a signal/condition is raised on any of the input pins of a Remote module an information packet will be transmitted. Any receiver in a distance of more or less three hundred meters will receive the signal. The remote monitor will search its memory for a valid serial number. When a valid number is found the Remote Monitor will log the input signal(s) of a particular Remote Module together with the current date and time into its memory. It will also send a response via its onboard RS232 interface to the host. A Client software package that is connected to IPCOMServer running on the host, interprets the Remote Monitors responses and displays them on a Graphical User Interface. The Remote Monitor has a wide range of applications, one of which is shown here. Custom remote modules can be designed by TIGME.COM to monitor computer rooms, weather stations, dams, temperature, air pressure, alarm systems, cameras and other remote control devices.
The second remote monitor application could be used with a device like a GSM module. The GSM module is attached to IPCOMServer. Remote GSM modules send updates to IPCOMServer. A Telnet client connected to IPCOMServer retrieves the information which is in SMS format. The Telnet Client can also send information to the module which can be sent to remote modules via SMS. One such practical application would be status monitoring of water pumps, alarms systems, weather stations, GPS updates. TIGME.COM design custom hardware and software programs for systems like this.
