Abstract: The short message service (SMS) is the most simple and convenient method for data communication in GSM system. The paper design and implement an dual communication system between the monitoring centre and the remote UPS and air conditioner by two TC35i modules. The system uses microcontroller AT89C52 to control and adjust remote UPS and the related circuits. Now the system runs well stably and reliably. It can be revised rarely and be applicable to the similar remote monitoring system
