Temperature Sensor with its Circuit Diagram

Working Principle of Arduino Temperature Sensor

Pseudocode

Let us see the construction of Arduino – Temperature Sensor. Here is a circuit diagram of the sensor. We can refer to it for making connections. Note that the temperature sensor has three pins.

Arduino – Temperature Sensor circuit


  • Pin 1(DC voltage): This pin is used for setting up the DC voltage pin to 5V on the Arduino UNO board.
  • Pin 2(Analog voltage output): This pin is responsible for generating the output of the measured temperature.
  • Pin 3(GND): This pin is used to set the ground level on Arduino using some reference voltage.

Connection of Arduino Temperature Sensor

Circuit connections of sensor

Note that the LM35 sensor has three terminals namely Vs, Vout, and GND. Each terminal has its significance and needs to be used carefully. These terminals are connected as follows:

  • Connect a wire to supply Vs with 5V, the connection must be made to the appropriate pin on Arduino.
  • Make a ground-to-ground connection from GND to GND on Arduino to set a reference level.
  • Connect the Vout to Analog zero on the Arduino board. This will give the output on the serial port.

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.
