Temperature Sensors

Temperature sensors are essential components in many applications, from industrial processes to consumer electronics. Understanding different types and their characteristics is crucial for proper selection and implementation.

Common Types
  • Thermistors (NTC/PTC)
  • Thermocouples
  • RTDs (Pt100/Pt1000)
  • Digital Temperature Sensors
  • Infrared Sensors
Implementation Example
// DS18B20 Digital Temperature Sensor
#include <OneWire.h>
#include <DallasTemperature.h>

OneWire oneWire(2);  // Data wire on pin 2
DallasTemperature sensors(&oneWire);

void setup() {
  sensors.begin();
}

float getTemperature() {
  sensors.requestTemperatures();
  return sensors.getTempCByIndex(0);
}
