Summary of Arduino Esplora Temperature Sensor
This project demonstrates how to read temperature data from the Arduino Esplora's built-in temperature sensor and send it to a computer via serial communication. By opening a serial connection at 9600 baud, the Esplora reads temperature values in Celsius or Fahrenheit using the Esplora.readTemperature() function. The data is then printed to the Serial Monitor for real-time monitoring. This simple setup requires only the Arduino Esplora and a USB connection to the computer.
Parts used in the Arduino Esplora Temperature Sensor project:
- Arduino Esplora
- USB cable
This sketch shows you how to read the Esplora’s temperature sensor. You can read the temperature sensor in Farhenheit or Celsius.
Circuit
Only your Arduino Esplora is needed for this example. Connect the Esplora to your computer with a USB cable and open the Arduino’s Serial Monitor.
Temperature to send data to your computer from the Esplora
Code
To send data to your computer, you need to open a serial connection. use Serial.begin() to open a serial port at 9600 baud on the Esplora.
The Esplora.readTemperature() function gets the value from the temperature sensor. It will give you the temperature in degrees Celsius or degrees Fahrenheit, depending on your choice. It takes one parameter, DEGREES_C for Celsius or DEGREES_F for Fahrenheit.
To send the values to the Serial Monitor, you call Serial.print(). When the Esplora is connected, and the Serial Monitor is open, you should start to see values reported like this:
Temperature is: 22 degrees Celsius, or 72 degrees Fahrenheit.
Fahrenheit = (9/5 * Celsius) + 32
Temperature is: 21 degrees Celsius, or 72 degrees Fahrenheit.
Fahrenheit = (9/5 * Celsius) + 32Hardware Required
