RANCANG BANGUN SISTEM MONITORING SUHU RUANGAN MENGGUNAKAN APLIKASI ISD 1420 BERBASIS MIKROKONTROLER AT89S51

The Design and Construction of System Monitoring Temperature Room Use Application ISD1420 Base on Mikrokontroler AT89S51 have been done. This system is designed so that can detect / monitoring change of temperature a room and also can give early warning which is application with output in the form of voice. This system consist of hardware and software. Hardware consist of a LM35 temperature censor along with lasing / amply, ADC0804, microcontroller, ISD1420 network used for the output of in the form of voice, software use assembly Ianguage to run microcontroller according to comand. Target of which will reach in final project is design a room temperature monitoring system use ISD application 1420 being based on AT89S51 microcontroller later on can be presented by computer. As a whole this room temperature monitoring system work and function as which in expecting. This appliance can do room temperature monitoring every moment, when there are increase of room temperature can give alarm in the form of voice through ISD1420 peripheral
