Which sensor is LM35?

LM35 is a temperature sensor. It outputs an analog voltage that is proportional to the ambient temperature in Celsius, typically about 10 millivolts per degree Celsius (so 25°C gives ~0.25 V). This linear voltage-to-temperature relationship makes it easy to read with a microcontroller’s ADC. It’s specifically designed for temperature measurement, unlike pressure sensors, humidity sensors, or touch sensors, which respond to different physical quantities.
