RANCANG BANGUN SISTEM MONITORING TEMPERATUR MULTICHANNEL PADA INSTRUMENTASI INDUSTRI DENGAN LM 35 MENGGUNAKAN MIKROKONTROLER MCS-51 BERBASIS WEB SERVER

Abstract

The research has been successfully design and realize monitoring temperature multichannel system with LM35 censor. This system good for knowing conditional of temperature where the censor put down. Monitoring temperature system using web server which can be accessed whenever with presented data by realtime. The appliance using 3 censor temperature use laboring LM35 by altering temperature parameter become tension with change of proportional tension with change of the temperature. Accepted data by censor later then altered in the form of digital use ADC networkso that can be processed by Microcontroller. Processing data system use Microcontroller AT89S51 which program with assembly language. Interfaced data to server computer through serial communications system. Data result of conversion immediately taken by server computer and delivered to user computer through LAN Network. At compuetr data user later then presented and released in the form of graph and number. Result of research shown at computer screen in the form of temperature gaph detected by temperature censor. The resultdata is publicized to pass server web facility so that all other user which connecting the network of data can be accesses. Data will be saved automatically in each every day commutations.
