The LM35 is a precision IC temperature sensor with a proportional output to temperature (in degrees Celsius). Because the sensor circuitry is enclosed, it is not susceptible to oxidation or other processes. The temperature can be monitored more precisely with the LM35 than with a thermistor.
It also has a low self-heating property, causing a temperature rise of less than 0.1 °C in still air. The temperature range for operation is -55°C to 150°C. The output voltage changes by 10mV for every °C change in ambient temperature, resulting in a scale factor of 0.01V/°C.
