how to connect lm35

Guys can someone give me hints on how to connect up LM 35 to my microprocessor 8051? and how would i program it if i wanted it to activate the buzzer if its temperature is higher den what is desired?
 

lm35 with 8051

lm35 is a temperature sensor with an analog output, 10mV per degree Celcius, as i recall the 8051 does not have an analog to digital converter, the in order to interface it you should use an analog to digital converter.

then the program is very straight forward as it is a matter of comparing a pair of bytes.

Hi,
LM35 is a Analog sensor, so you must use ADC(Analoge to Digital Convertor) device.
i think 8051 have this itself.
so you must go to learn how to Use ADC in 8051
it's so simple....

Good Luck...
