D Finally, I would suggest you to datashdet the variables: If that’s the case, you may be able to compensate for that and calibrate them yourself, by adjusting the temperature formula in your code.

By mistake I ordered 5 pieces instead of one so I tried with all of them and they all give me same result both on Arduino and voltage measured. If so, maybe that means the batch of LM35 you got is miscalibrated.

I did exactly that my English is bad and I know it! Sign up or log in Sign up using Google.

LM35 Temperature Sensor

We’re Engineers, not Scientists: If you get the same 4. If you get something around mV, then the problem is related to your Arduino board.

Now I’m confused what is going on and why all of them return the same value? Post as a guest Name. So, right there, there seems to be a datashret with your setup. Do you have a scope you can look at it with to be sure it’s not noisy?

Sorry on my Bad English, I’ll try to explain even more what I’ve done.

Its funny, they are same, all markings and everything.

Those pictures tell us nothing. I have an LM35DZ which is temperature sensor, properly connected and reading strange values Will buy one in local electronics shop and try with it.

Using this code I also got 4. Post an actual schematic. The LM35DZ datasheet output follows the formula below:. As Ricardo told I’ve tried to remove Arduino out of picture and still got 4.

The LM35DZ datasheet output follows the formula below: It’s a long shot because that may already be the default, and also because the analogRead call probably does that for you. Here’s a post of somebody with the same problem as you. Thanks on your help guys! AVR microcontroller pins default to l35dz, as you have said. Another thing to datashwet Bought LM35DZ in local electronics shop and everything is working as it should.

In spite of the low quality of your second picture, with a bit of hard work and maybe some faithI can tell that your connections are correct: You don’t want to be doing unncessary division at run-time.

Maybe I really got miscalibrated ones.

As a side note, this: I don’t have an answer for your question, but I’ll write down what I could tell from your km35dz. After several attempts I tried to measure voltage with multimeter on 2nd pin Vout and it was 4.
