LM35 temperature conversion

[projectplasma]

Hello.The LM35 thermal sensor has a range of -55 to 150C.The general equation used to convert output voltage to temperature is:

* Temperature ( oC) = Vout * (100 oC/V)
* So if Vout is 1V , then, Temperature = 100 oC

Now what I want to know is,what will be the voltage output in the voltmeter when the temperature being sensed is -10C? Or for that matter,any subzero temperature?Please help me out.Thanks.

Hi Projectplasma,

Look at the datasheet page 7, figure 7:

The output voltage will be also 10mV/°C.
At -10°C the output voltage will be -100mV.
