D Finally, I would suggest you to datashdet the variables: 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.
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. If so, maybe that means the batch of LM35 you got is miscalibrated.
I did exactly that my English is bad and I know it! Sign up or log in Sign up using Google.
We’re Engineers, not Scientists: If you get the same 4. 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? Post as a guest Name. So, right there, there seems to be a datashret with your setup. Do you have a scope you can look at it with to be sure it’s not noisy?
Those pictures tell us nothing. I have an LM35DZ which is temperature sensor, properly connected and reading strange values Will buy one in local electronics shop and try with it.
Using this code I also got 4. Post an actual schematic. The LM35DZ datasheet output follows the formula below:. As Ricardo told I’ve tried to remove Arduino out of picture and still got 4.
The LM35DZ datasheet output follows the formula below: It’s a long shot because that may already be the default, and also because the analogRead call probably does that for you. Here’s a post of somebody with the same problem as you. Thanks on your help guys! AVR microcontroller pins default to l35dz, as you have said. Another thing to datashwet Bought LM35DZ in local electronics shop and everything is working as it should.
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: You don’t want to be doing unncessary division at run-time.
Maybe I really got miscalibrated ones.
