Temperature Sensor
The following code example requires two additional libraries. These consist of the
OneWire Library
by
Paul Stoffregen
, published under the MIT License, and the
Dallas Temperature Control Library
by
Miles
Burton
, published under the LGPL License. Both libraries are included in the package and must be copied
to the "library" folder before starting the Arduino IDE. You can find it by default under the following path
of your Windows installation: C:\Users\[Username]\Documents\Arduino\libraries
You can download the code example for Arduinos
here
or copy the following one:
3. CODE EXAMPLE ARDUINO
// Required libraries are imported
#include <DallasTemperature.h>
#include <OneWire.h>
// The input pin to which the sensor module is connected is declared here.
#define KY001_Signal_PIN 4
// Libraries are configured

void
setup
() {
// Initialization Serial output
Serial.begin(
9600
);
Serial.println("KY

001 Temperaturmessung");
// Sensor is initialized
sensors.begin();
}
// Main program loop
void

{
// Temperature measurement is started...
sensors.requestTemperatures();
// ... and display measured temperature
Serial.print("Temperatur: ");
Serial.print(sensors.getTempCByIndex(
0
));
Serial.write(
176
);
// UniCode specification of a char symbol for the "° symbol".
Serial.println("C");
delay(
1000
);
// 5s Pause until next measurement
}
