LM35 Temperature Sensor for Arduino

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 to provide typical accuracies of ±¼°C at room temperature and ±¾°C over a full -55 to +150°C temperature range

Features:
# Calibrated directly in ° Celsius (Centigrade)
# Linear + 10.0 mV/°C scale factor
# 0.5°C accuracy guaranteeable (at +25°C)
# Rated for full -55° to +150°C range
# Suitable for remote applications
# Low cost due to wafer-level trimming
# Operates from 4 to 30 volts
# Less than 60 µA current drain
# Low self-heating, 0.08°C in still air
# Nonlinearity only ±¼°C typical
# Low impedance output, 0.1 Ohm for 1 mA load
