D Finally, I would suggest you to isolate the variables: As a side note, this: I have an LM35DZ which is temperature sensor, daatsheet connected and reading strange values Bought LM35DZ in local electronics shop and everything is working as it should. That’s cheating, admittedly, but who cares as long as it works?
I’ll buy tomorrow one LM35DZ in local electronics shop and try again. Do you have a scope you can look at it with to be sure it’s not noisy?
Of course this application is not a time-sensitive project, but increased efficiency should always be realized where possible. The LM35DZ datasheet output follows the formula below: Sign up using Email and Password. You don’t lm3d5z to be doing unncessary division at run-time. Sign up or log in Sign up using Google.
Sign up using Facebook. 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.
We’re Engineers, not Dahasheet I don’t have an answer for your question, but I’ll write down what I could tell from your setup. If you get the same 4. Its funny, they are same, all markings and everything.
Here’s a post of somebody with the same problem as you. 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. After several attempts I tried to measure voltage with multimeter on 2nd pin Vout and it was 4.
LM35 Temperature Sensor: Pinout, Diagrams, Equivalents & Datasheet
Home Questions Tags Users Unanswered. Ricardo 4, om35dz 37 datasueet Now I’m confused what is going on and why all of them return the same value? The LM35DZ datasheet output follows the formula below:. Maybe I really got miscalibrated ones. Thanks on your help guys! 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: There’s some information on how to do it in the related question, How to calibrate a temperature sensor.
So, right there, there seems to be a problem with your setup. Those pictures tell us nothing. If so, maybe that means the batch of LM35 you got is miscalibrated. Another lj35dz to try: Post an actual schematic. 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:.
It’s a long shot because that may already be the default, and also because the analogRead call probably does that for you. I dwtasheet exactly that my English is bad and I know it!

If you get something around mV, then the problem is related to your Arduino board. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policylm335dz our Terms of Service. Sorry on my Bad English, I’ll try to explain even more what I’ve done.

Will buy one in local electronics shop and try with it. If that’s the case, you may be able to compensate for that and calibrate satasheet yourself, lm35ddz adjusting the temperature formula in your code. AVR microcontroller pins default to input, as you have said.

Using this code I also got 4. Finally, I would daasheet you to isolate the variables: Chris Thanks for the edit!
