temperature sensor lm35 (how it works)

[RADHIKAMANI]

hi am doing temperature sensor(LM35) in my project,i want to know in what principle it's work (like thermistor,thermocouple)
if any body knows means reply me...

and also tell about the one moisture sensor for better performance....


thank you...

Do you want to know the internal mechanisms of its workings? Or do you want to know how you have to use it, eg. the output it gives for different temperatures, temperature ranges, how to measure the output, etc?

Basically it is a precise temperature sensor which has 3 main connectors. VCC, GND and OUTPUT. The first and second are fix values of your circuit and the third , it means the OUTPUT provides a voltage proportional to the temperature. Then you can connect a resistance in serie and measure also the current of this voltage variation.

hope it helps,
