It’s a long shot because that may already be the default, and datssheet because the analogRead call probably does that for you.
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:.
We’re Engineers, not Scientists: 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?
That’s cheating, admittedly, but who cares daatsheet long as it works? Sign up using Facebook. As a side note, this: Chris Thanks for the edit!

Using this code I also got 4. Home Questions Tags Users Unanswered. If you get the same 4. Here’s a post of somebody with the same problem as you.

Its funny, they are same, all markings and everything. Bought LM35DZ in local electronics shop and everything is working as it should.
Do you have a scope you can look at it with to be sure it’s not noisy? Thanks on your help guys! Sorry on my Bad English, I’ll try to explain even more what I’ve done. I did exactly that my English is bad and I know it!
The LM35DZ datasheet output follows the formula below:. Another thing to try: If so, maybe that means the batch of LM35 you got is miscalibrated. Ricardo 4, 14 37 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: The LM35DZ datasheet output follows the formula below: There’s some information on how to do it in the related question, How to calibrate a temperature sensor.
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. Sign up using Email and Password. There’s got to be something in your hardware, but I don’t know what it is.

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. So, right there, there seems to be a problem with your setup.
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. You don’t want to be doing unncessary division at run-time. Will buy one in local electronics shop and try with it. AVR darasheet pins default to input, as you have said.
