Temperature is a significant part of our daily life. Too high Temperature and too Low temperature are not comfortable for human as well as electronics around us.
This can be controlled by having an airflow around our system. Airflow can cool down our system and also stable our temperature.
For temperature sensing, we use LM35 which is a low-cost and precise sensor with easy operations.
Detailed Temperature sensing can be found here
For proper operation, we have to average some samples of temperature so in this tutorial we are using 100 samples.
As total Resolution of 0 – 5V is from 0 to 1023 we can have 4.88 mV ( 5/1023 V)
Now LM35 shows 10mV increase per degree Celsius so one reading of value ( 0 – 1023) shows 0.488 degree Celsius ( 4.88 / 10 degree Celsius)
Therefore total Temperature is 0.48 * Value.
