Here’s a post of somebody with the same problem as you. We’re Engineers, not Scientists: 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. So, right there, there seems to be a problem lm3d5z your setup.

That’s cheating, admittedly, but who cares as long as it works? Those pictures tell us nothing.

AVR microcontroller pins default to input, as you have said. Another thing to try: Do you have a scope you can look at it with to be sure it’s not noisy? Of course this application adtasheet not a time-sensitive project, but increased efficiency should always be realized where possible.

Thanks on your help guys!

Finally, I would suggest you to isolate the variables: After several attempts I tried to measure voltage with multimeter on 2nd pin Vout and it was 4. Post an actual schematic. Sign up using Facebook.

If so, maybe that datasheer the batch of LM35 you got is miscalibrated. I’ll buy tomorrow one LM35DZ in local electronics shop and try again. If you get the same 4. It’s a long shot because that may already be the default, and also because the analogRead call probably does that for you. Using this code I also got 4. Sign up or log in Sign up using Google. If you get something around mV, then the problem is related to your Arduino board.

I did exactly that my English is bad and I know it! The LM35DZ datasheet output follows the formula below:.

Sorry on my Bad English, I’ll try to explain even more what I’ve done. I have an LM35DZ which is temperature sensor, properly connected and reading strange values Now I’m confused what is going on and why all of them return the same value?

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. I also second your recommendation – I remove the Arduino and measure the output as a function of varying lengths of time you heat the device with your hands. Chris Thanks for the edit! Sign up using Email and Password. In spite of the low quality of your second picture, with datasheet bit of hard work and maybe some faithI can tell that your connections are correct:.

I don’t have an answer for your question, but I’ll write down what I could tell from your setup.

As Ricardo told I’ve tried to remove Arduino out of picture and still got 4. Post as a guest Name. Bought LM35DZ in local electronics shop and everything is working as it should.

Maybe I really got miscalibrated ones. In spite of the low quality of your second picture, with a bit of lm335dz work and maybe some faithI can tell that your connections are correct: The LM35DZ datasheet output follows the formula below: You don’t want to be doing unncessary division at run-time.

Will buy one in local electronics shop and try with it. There’s got to be something in your hardware, but I don’t know what it dafasheet.
