Working Principle of Arduino Temperature Sensor
The idea behind temperature detection is to use a simple formula which is given by
ADC Value = sample * 1024 / reference voltage (+5v)
The temperature sensor LM35 sensor is used for detecting the temperature and sending this value to the Arduino. The Analog Digital Converter (ADC) is used to convert input analog values into a digital approximation using the formula provided above. When a +5 voltage is provided at the input, the digital approximation will be equal to
ADC Value = input voltage * 1024/4 so ADC Value = input voltage * 205
Arduino – Temperature Sensor
Sensors are widely used for sensing different quantities and quantifying them. One such example of a sensor is the temperature sensor which uses Arduino for displaying this temperature. The main feature of this sensor is that it can display the detected temperature on a Celsius scale.
In this article, we will study how to design this Temperature Sensor using the Arduino board and programming software. We will study the specifications needed for this sensor, and the methods and circuit diagrams used for designing this sensor. In addition to this, we will see the Arduino code written on IDE that will result in a sensor.
