In spite of the low quality of your second picture, with a bit of hard work and maybe some faithI km35dz tell that your connections are correct:. Post an actual schematic.
If you get something around mV, then the problem is related to your Arduino board. Bought LM35DZ in local electronics shop and everything is working as it should.
You don’t want to be doing unncessary division at run-time. I did exactly that my English is bad and I know datasheett
If so, maybe that means the batch of LM35 you got is miscalibrated. Post as a guest Name. Of course this application is not a time-sensitive project, but increased efficiency should always be realized where possible.
As Ricardo told I’ve tried to remove Arduino out of picture and still got 4. Its funny, they are same, all markings and everything.
Sign up or log in Sign up using Google. I also second your recommendation – I remove datashert Arduino and measure the output as a function of varying lengths of time you heat the device with your hands.
Maybe I really got miscalibrated ones. There’s got to be something in your hardware, but I don’t know what it is. Thanks on your help guys!
After several attempts I tried to measure voltage with multimeter on 2nd pin Vout and it was 4. D Finally, I would suggest you to isolate the variables: It’s a long shot because that may already be the default, and also because the analogRead call probably does that for you.
LM35 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. Lm35fz Thanks for the edit! Email Required, but never shown. So, right there, there seems to be a problem with your setup.
The LM35DZ datasheet output follows the formula below: AVR microcontroller pins default to input, as you datashret said. If you get the same 4.

Those pictures tell us nothing. 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. Sorry on my Bad English, I’ll try to explain even more what I’ve done. Sign up using Facebook.
That’s cheating, admittedly, but who cares as long as it works?
