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: 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.

Sorry on my Bad English, I’ll try to explain even more what I’ve done. Home Questions Tags Users Unanswered. AVR microcontroller pins default to input, as you have said. Email Required, but never shown. Will buy one in local electronics shop and try with it.

Now I’m confused what is going on and why all of them return the same value? I did exactly that my English is bad and I know it! I have an LM35DZ which is datsaheet sensor, properly connected and reading strange values The LM35DZ datasheet output follows the formula below:.

Ricardo 4, datasheeh 37 I don’t have an answer for your question, but I’ll write down what I could tell from your setup.

LM35 Temperature Sensor

Of course this application is not a time-sensitive project, but increased efficiency should always be realized where possible. Maybe I really got miscalibrated ones. If you get the same 4. You don’t want to be doing unncessary division at run-time. As Ricardo told I’ve tried to remove Arduino out of picture and still got 4.

temperature – Arduino LM35DZ giving incorrect voltage – Electrical Engineering Stack Exchange

If you get something around mV, then xatasheet problem is related to your Arduino board. Post an actual schematic. Its funny, they are same, all markings and everything. D Finally, I would suggest you to isolate the variables: Sign up using Facebook.

Bought LM35DZ in local electronics shop and everything is working as it should. So, right there, there seems to be a problem with your setup.

Post as a guest Name. After several attempts I tried to measure voltage with multimeter on 2nd pin Vout and it was 4.

There’s some information on how to do it in the related question, How to calibrate a temperature sensor. As a side note, this:
