Tutorial: How to Use DS18B20 Temperature Measurement Sensor Module KY-001

The DS18B20 sensor module is a simple and reliable device for measuring temperature in degrees Celsius. Ideal for DIY projects, 3D printers, drones, or any application requiring precise temperature readings.

What you need

• Arduino Uno
• USB A-Micro B cable
• Batter

Steps

1. Connect the DS18B20 module to the data pin of the Arduino microcontroller
2. Install the OneWire and DallasTemperature libraries through the Arduino IDE
3. Load the example sketch provided in the DallasTemperature library
4. Verify that the LED on the module lights up when a temperature reading request is sent
5. Modify the sketch to display the temperature on an LCD or OLED display connected to the Arduino microcontroller
6. Test the sensor by exposing it to different temperatures and observing the changes on the display
7. Implement periodic data acquisition (for example, every minute) for continuous monitoring
8. Save temperature data to an SD network or send it online via Wi-Fi

Example code

// Includi le librerie necessarie
#include <OneWire.h>
#include <DallasTemperature.h>
// Definisci il pin del sensore DS18B20
#define ONE_WIRE_BUS 2
// Oggetti per la libreria DallasTemperature
OneWire oneWire(ONE_WIRE_BUS);
DallasTemperature sensors(&oneWire);
void setup(void) {
  Serial.begin(9600); // Inizializza la comunicazione seriale
}
void loop(void) {
  sensors.requestTemperatures(); // Richiedi le temperature ai sensori DS18B20
  float temperatura = sensors.getTempCByIndex(0); // Ottieni la temperatura in gradi Celsius dal primo sensore
  Serial.print("Temperatura: ");
  Serial.println(temperatura);
  delay(5000); // Attendi 5 secondi prima di rilevare nuovamente la temperatura
}

Mini project

Create a thermal alarm system that sends an email or SMS notification when the temperature exceeds a certain critical value. Use the DS18B20 module to measure the temperature and an online service like IFTTT to send notifications.
