The LM35DZ datasheet output follows the formula below: If so, maybe that means the batch of LM35 you got is miscalibrated. Will buy one in local electronics shop and try with it. Sorry on my Bad English, I’ll try to explain even more what I’ve done. Bought LM35DZ in local electronics shop and everything is working as it should.

If you get the same 4. Maybe I really got miscalibrated ones. AVR microcontroller pins default to input, as you have said. You don’t want to be doing unncessary division at run-time.
There’s got to be something in your hardware, but I don’t know what it is. I did exactly that my English is bad and I know it! Post an actual schematic. I don’t have an answer for your question, but I’ll write down what I could tell from your setup.
LM35 Temperature Sensor
D Finally, I would suggest you to isolate the variables: As Ricardo told Dagasheet tried to remove Arduino out of picture and still got 4. Those pictures tell us nothing. 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: So, right there, datasbeet seems to be a problem with your setup.
That’s cheating, admittedly, but who cares as long as it works? Using this code I also got 4.
LM35 Temperature Sensor – Datasheet & Pin Diagram
In spite of the low quality of your datsaheet picture, with a bit of hard work and maybe some faithI can tell that your connections are correct:. Finally, I would suggest you to isolate the variables: Thanks on your help guys!
After several attempts I tried to measure voltage with multimeter on 2nd pin Vout and it was 4.
Email Required, but datzsheet shown. As a side note, this: Ricardo 4, 14 37 Of course this application is not a time-sensitive project, but increased efficiency should always be realized where possible. Lm35da 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. If you get something around mV, then the problem is related to your Arduino board. Its funny, they are same, all markings and everything.

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. Do you have a scope you can look at it with to be sure it’s not noisy? Chris Thanks for the edit! Now I’m confused what is going on and why all of them return the same value?
