LM35 Temperature Sensor based Temperature Monitoring System with Arduino UNO and LCD Display

In this project, we will design a LM35 Temperature Sensor based Temperature Monitoring System with Arduino UNO and LCD Display. Here, we will measure the temperature of the surrounding or any other material to which the LM35 temperature sensor is connected for its temperature measurement and we will display the temperature value in degree centigrade in a 16X2 alphanumeric LCD. But, the output of LM35 temperature sensor is analog in nature and  Arduino UNO cannot process the analog signal directly. So, first it will convert the analog output of LM35 temperature sensor to digital values using its analog to digital converter and then it process the digital value to convert the digital value in degree centigrade value. Then the Arduino UNO will display the temperature in degree centigrade in the 16X2 alphanumeric LCD. Now, lit a match stick or lighter near the LM35 temperature sensor and see the changes in its output value in the 16X2 alphanumeric LCD.
