The LM35 Analog Temperature Sensor is a popular option for temperature sensing over the range of -55 to 150°C.

• LM35 Temperature Sensor

• Provides analog output directly readable in degrees Celsius
• Output voltage corresponds to 10.0mV/°C
• -55 to 150°C measurement range with ±0.5°C accuracy°
• 5V compatible.  3.3V uC compatible if the sensor is run off separate 4 to 20V supply.

If you have a uC like an Arduino and you want to measure temperature, the LM35 is one of the more popular temperature measurement ICs to use.

The LM35 is a 3-pin analog thermometer packaged in a TO-92 package.  The output is a linear voltage that corresponds to 10.0mV/°C, so the output is directly readable in degrees Celsius using an analog port on a uC.  Accuracy is typically within 0.5°C.

Since the voltage output range of the sensor is limited to 1.5V, if a greater resolution is desired, the analog reference voltage on the uC can be changed from the default 5V to something closer to 1.5V which will decrease the voltage step size on the analog readings.

Hook-up is very simple.  Connect GND pin to ground, Vs pin to 5V (or anything between 4 – 20V) and Vout pin to an analog pin on the uC.  The device can be left open air for measuring air temps or it can be glued or cemented to an object that you want to measure the temperature of such as a heat sink.

When using the LM35 with a single supply voltage, the temperature measurement range is limited to 2°C to 150°C which is adequate for most applications.  If the negative range is required, see the datasheet for specifics.

An alternative for temperature measurement is to use a digital temperature sensor like the DS18B20 which comes in the same package.  Digital temp sensors tend to have better noise immunity which is useful when the sensor will be placed some distance away or is in an electrically noisy environment, but they do require a software library to implement the communication protocol.  Libraries are readily available for most common microcontrollers such as the Arduino and are very straightforward to use.
