Scroll down to compare the LM35/LM35DZ temperature sensor price at different stores.
The LM35 (also known as LM35DZ) is a linear temperature sensor that outputs a voltage proportional to the temperature value in Celsius (ºC). It outputs 10mV per degrees Celsius rise in temperature. It can be powered with 5V – ideal to interface with Arduino.
