LM35 Temperature Sensor
Sign up using Email and Password. If so, maybe that means the batch of LM35 you got is miscalibrated. Thanks on your help guys! The LM35DZ datasheet output follows the formula below:.
LM35 Temperature Sensor
Another thing to try: Email Required, but never shown. Will buy one in local electronics shop and try with it.
Of course this application is not a time-sensitive project, but increased efficiency should always be realized where possible. That’s cheating, admittedly, but who cares as long as it works?
Chris Thanks for the edit! As a side note, this: I don’t have an answer l3m5dz your question, but I’ll write down what I could tell from your setup.
Ricardo 4, 14 37 Here’s a post of somebody datasbeet the same problem as you. So, right there, there seems to be a problem with your setup.
Sorry on my Bad English, I’ll try to explain even more what I’ve done. If you get the same 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.
LM35 Temperature Sensor: Pinout, Diagrams, Equivalents & Datasheet
There’s some information on how to do it in the related question, How to calibrate a temperature sensor. As Ricardo told I’ve tried to remove Arduino out of picture and still got 4. 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.
Maybe I really got miscalibrated ones. We’re Engineers, not Scientists: Post an actual schematic. After several attempts I tried to lm35rz voltage with multimeter on 2nd pin Vout and it was 4. 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. 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 did exactly that my English is bad and Datasheeet know it!
