Temperature Monitoring System using 89V51


P89v51RD2 of NXP is having a inbuilt boot loader which makes the programming of p89v51rd2 very simple. For that connect EA pin to Vcc and PSEN Pin to ground. And use Flash Magic Software for downloading your hex file using a MAX232




In this design ADC808 is interfaced with micro controller 89v51 to read the Temperature from LM35 and displayed on an LCD Interfacing ADC808 <
