This simulation has been created on Proteus 8 and the libraries used are easily available on the internet It provides output voltage in Centigrade (Celsius). Input voltage is +5V for typical applications, There will be increase in 10mV for raise of every 1°C. TEMP = (celcius*9/5) + 32; Serial.print("Temperature is "); Serial.println(TEMP); delay(1000); } Here is the code of LM35. This means that the output voltage is proportional to the temperature. I gues that termister is simple THERM-ally sensitive res-ISTOR, but LM35 has some amplifying element inside. Using arduino mini pro and Voltage for me is 5Vchecked wiring, plus , GND , and output are set correctly, I kept serial.println only for celsius ... there are 21 degrees in room, Reply The output voltage varies by 10 mV in response to every oC rise/fall in ambient temperature, i.e., its scale factor is 0.01 V/ oC.
