design temperature sensor

[kelvini]

any suggestion on how to design a temperature sensor using ADC, lm35 n microcontroller....

LM35 is a sensor itself, connect to the ADC input pin of your microcontroller, output is 10mV/C

 

[rthilip]

Give the inputs of LM35 to an ADC ar any microcontroller with inbuilt ADC. If u r giving the input to any external adc, give the pulse from IC555 to its clock i/p.

You can use DS18S20 digital termo. it's cool with memory, alarm, and single wire interface.

Try it

what components i can add on if i wanna use four 7segments as output?
seems like i'm running out of ports....

 

[abbas1707]

designing a temperature sensor is some thing different....dont you think so

I would suggest you to use an OPAMP to condition the sensor to the scale to which the ADC responds and then interface it .

another option:
u can also use voltage divider network for this purpose

Since the O/p of the sensor is too small we cant chop it down anyfurther.
