LM35 Analog Temperature Sensor
The LM35 series are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. The LM35 thus has an advantage over linear temperature sensors calibrated in Kelvin, as the user is not required to subtract a large constant voltage from its output to obtain convenient Centigrade scaling. The LM35 does not require any external calibration or trimming over a full -55 to +150 °C temperature range.

Calibrated directly in ° Celsius (Centigrade)
Linear +10.0 mV/°C scale factor
0.5 °C accuracy guaranteeable (at +25 °C)
Suitable for remote applications
Low cost due to wafer-level trimming
Less than 60 mA current drain
Low self-heating, 0.08 °C in still air
Low impedance output, 0.1Ω for 1 mA load
