LM35 is a precision centigrade temperature sensors, It shows values in the form of output voltages instead of degree Celsius. LM35 shows high voltage values than thermocouples and may not need that the output voltage is amplified.
The output voltage of LM35 is proportional to the Celsius temperature. The scale factor is .01 V/°C. One most important characteristic is that it draws just 60 microamps from its supply and acquires a low self-heating capacity.
LM35 temperature sensor available in many different packages like T0-46 metal transistor-like package, TO-92 plastic transistor-like package, 8-lead surface mount SO-8 small outline package.

LM35 is a precession Integrated circuit Temperature sensor, whose output voltage varies, based on the temperature around it. It is a small and cheap IC which can be used to measure temperature anywhere between -55°C to 150°C. It can easily be interfaced with any Microcontroller that has ADC function or any development platform like Arduino.
Power the IC by applying a regulated voltage like +5V (VS) to the input pin and connected the ground pin to the ground of the circuit. Now, you can measure the temperate in form of voltage as shown below.
If the temperature is 0°C, then the output voltage will also be 0V. There will be rise of 0.01V (10mV) for every degree Celsius rise in temperature. The voltage can converted into temperature using the below formulae.
●Used for measuring the temperature of a particular environment.
●Used in Power Supplies
●Used in Battery Management
●Used in HVAC
●Used in Appliances
●Used in Monitoring Battery Temperature
●Used in HVAC applications as a temperature measurement device.
●It provides thermal shutdown for a circuit/component
●It provides thermal shutdown for a circuit or component used in a specific project.
●It provides battery protection from overheating.
