SHT1x sht1x;

void setup() {
  Serial.begin(9600);
}

void loop() {
  float temperature = sht1x.readTemperature();
  float humidity = sht1x.readHumidity();
  Serial.print("Temperatura: ");
  Serial.print(temperature);
  Serial.print("°C, Humidità: ");
  Serial.print(humidity);
  Serial.println("%");
}
```

Mini project

Build a simple temperature and humidity monitor. Connected to an LCD display to show the data.

Common mistakes

• Connect VCC correctly to 5V and GND to GND.
• Check that the SDA and SCL frequency is correct.
• Ensure the SHT1x library is installed.
• Check serial communication with Serial Monitor.

Recommended accessories

• 16×2 LCD Display
