On a sunny hot day, you all might have thought what's the temperature and might have checked on the phone. But did you ever thought that is it actually correct or not?. I also check the temperature every day but it feels like fake and I don't believe the weather forecast since what they say never happens.
So why don't we make your thermometer to check the real-time temperature at your location? Let's make a temperature device using #Arduino and #temperature sensor LM35. it comes in three edition- LM35A, LM35C, LM35D. The main difference is the temperature range-
LM35A has the widest range of -55 degrees Celcius to 155-degree Celcius.
LM35C has a lesser range of -40 degrees Celcius to 110-degree Celcius.
LM35D has the shortest range of 0 degrees Celsius to 100 degrees Celsius.
Hardware required:
Arduino board: Any Arduino board will work either in be UNO or MEGA or NANO or any other. Since all have the same functionality. We used an Arduino UNO.

LM35: It's a temperature sensor, you can choose any variant depending on your use.

A Breadboard: A breadboard is a rectangular plastic board with a bunch of tiny holes in it. These holes let you easily insert electronic components to prototype to an electronic circuit since they are internally connected as rows and columns.

Jumper wire: A jumper wire is an electrical wire, or group of them in a cable, with a connector or pins at each end used to connect component, sensors, etc to a breadboard they are of three types male to female, female to female, and male to male.here we need male to male jumper wires.

Circuit :
You just have to connect LM35 to an Arduino board in this simple way: -
