Tutorial: How to Use the SHTC3 Temperature and Humidity Sensor

The SHTC3 is a high-precision digital temperature and humidity sensor, ideal for environmental monitoring projects. Connect it easily to a microcontroller for precise temperature and humidity measurement.

What you need

• Arduino or Compatible Microcontroller
• USB Cable
• Jumper Wire
• Arduino IDE Software

Steps

1. Connect the SHTC3 to the microcontroller using jumper wires. The VCC and GND pins must be connected to the +5V and GND of the microcontroller respectively. The SDA pin should be connected to the A4 (SDA) pin of the microcontroller and the SCL pin to the A5 (SCL) pin.
2. Open the Arduino IDE software and install the Adafruit_SHTC3 library.
3. Include the Adafruit_SHTC3 library in your code.
4. Create an SHTC3 object and initialize it.
5. Use the readTemperature() and readHumidity() functions to read the temperature and humidity values.
6. Send the read data to the serial monitor to display it.
7. Check the values on the serial monitor to ensure the sensor is working correctly.
8. Modify your project to integrate the sensor data into a more complex application.

Example code

Adafruit_SHTC3 shtc3;

void setup() {
  Serial.begin(9600);
  if (!shtc3.begin()) {
    Serial.println(F("Errore durante l'inizializzazione del sensore"));
    while (1);
  }
}

void loop() {
  float temperature = shtc3.readTemperature();
  float humidity = shtc3.readHumidity();
  Serial.print("Temp: ");
  Serial.print(temperature);
  Serial.print(" C, Humidity: ");
  Serial.print(humidity);
  Serial.println(" %");
  delay(2000);
}

Mini project

Create a humidity alarm system that sends a message when the humidity exceeds a certain limit.

Common mistakes
