Esplora Temperature Sensor
This sketch shows you how to read the Esplora's temperature sensor. You can read the temperature sensor in Farhenheit or Celsius.
Hardware Required
- Arduino Esplora
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) + 32

#include <Esplora.h>
void setup() {
Serial.begin(9600); // initialize serial communications with your computer
}
void loop() {
// read the temperature sensor in Celsius, then Fahrenheit:
int celsius = Esplora.readTemperature(DEGREES_C);
int fahrenheit = Esplora.readTemperature(DEGREES_F);
// print the results:
Serial.print("Temperature is: ");
Serial.print(celsius);
Serial.print(" degrees Celsius, or ");
Serial.print(fahrenheit);
Serial.println(" degrees Fahrenheit.");
Serial.println(" Fahrenheit = (9/5 * Celsius) + 32");
// wait a second before reading again:
delay(1000);
