RANCANG BANGUN PENGUKURAN TEMPERATUR JARAK JAUH VIA SMS BERBASIS MIKROKONTROLER ATMega8535

Abstract

Have been done desain system for measurement long distance temperature by Short Message Service using microcontroller of ATMega8535. This desain system could detect temperature in one place and send it by SMS (Short Message Service). This Engineering could be used for measurement the another job. This Engineering contains Transmit Station and Receive Station. Transmit Station had been related with microcontroller ATMega8535 with Transmiter Handphone. Transmit station consist of temperature sensor LM35, signal conditioning, external timer, microcontroller AVR ATMega8535 with internal Analog to Digital Converter configuration. Receiver Station consist of Receiver Handphone and Personal Computer with Visual Basic 6.0 program. This Engineering detect temperature in one place and converted to digital format and Protocol Data Unit format and then send it using serial interfacing to Transmiter Handphone. To control time delayed of temperature measurement deliver had been done by external timer of 555 for 15 minutes delayed. Acqousition of temperature measurement would be received by receiver handphone wich related with Personal Computer and Visual Basic 6.0 program.
