What is temperature sensor LM35?
What is temperature sensor LM35?
LM35 is a temperature measuring device having an analog output voltage proportional to the temperature. It provides output voltage in Centigrade (Celsius). It does not require any external calibration circuitry. The sensitivity of LM35 is 10 mV/degree Celsius. As temperature increases, output voltage also increases.

What is output of LM35 at 27 degree Celsius?
The output of LM35 linearly varies with the temperature that is 10mV per degree C . So for room temp ie 27 degree C , 270 mV will be observed on the DMM.
What is LM 35 temperature sensor?
LM35 is a precession Integrated circuit Temperature sensor, whose output voltage varies, based on the temperature around it. It is a small and cheap IC which can be used to measure temperature anywhere between -55°C to 150°C. It can easily be interfaced with any Microcontroller that has ADC function or any development platform like Arduino.
How does lm35 work?
Lm35 is a temperature sensor that outputs an analog signal. In principle, the sensor will perform sensing when the temperature changes every 1 ºC temperature will show a voltage of 10 mV. In placing the. temperature (measured in Kelvin) into either Fahrenheit or Celsius, depending on the part (LM34 or LM35).
What is linear monolithic in lm35 sensor?
The LM35 is a sensor that measures temperature. The Prefix LM stands for Linear Monolithic. Temperature is an important parameter that is commonly measured. From weather systems, to air conditioning units, temperature sensors are an essential part of everyday life.
