LM35DZ Datasheet(PDF) – National Semiconductor (TI)
Of course this application is not a time-sensitive project, but increased efficiency should always be realized where possible. Chris Thanks for the edit! As Ricardo told I’ve tried to remove Arduino out of picture and still got 4.
It’s a long shot because that may already be the default, and also because the analogRead call probably does that for you. Bought LM35DZ in local electronics shop and everything is working as it should.
Now I’m confused what is going on and why all of them return the same value?

Home Questions Tags Users Unanswered. That’s cheating, admittedly, but who cares as long as it works? If that’s the case, you may be able to compensate for that and calibrate them yourself, by adjusting the temperature formula in your datashee.

Here’s a post of somebody with the same problem as you. Will buy one in local electronics shop and try with it. The LM35DZ datasheet output follows the formula below:.
I’ll buy tomorrow one LM35DZ in local electronics shop and try again. After several attempts I tried to measure voltage with multimeter on 2nd pin Vout and it was 4.
If you get something around mV, then the problem is related to your Arduino board. 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:.
Do you have a scope you can look at it with to be sure it’s not noisy? I did exactly that my English is bad and I know it!
I don’t have an answer for your question, but I’ll write datasheer what I could tell from your setup. Maybe I really got miscalibrated ones.
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. There’s got to be lm5dz in your hardware, but I don’t know what it is. Ricardo 4, 14 37 There’s some information on how to do it in the related question, How to calibrate a temperature sensor.
We’re Engineers, not Scientists: Using l35dz code I also got 4.
