• SKU: ARD0011891
• Price: 5.55 €

What it is for

The SHT20 module finds application in a wide range of projects, including: environmental monitoring, humidity control in greenhouses or closed environments, alarms for critical environmental conditions (high/low temperature or humidity). Its compatibility with Arduino and other microcontrollers makes it easy to use in DIY and prototyping projects.

Tutorial: How to Use SHT20 Temperature and Humidity Sensor Module

The SHT20 module is a high-precision digital sensor for measuring temperature and relative humidity. Ideal for environmental monitoring projects, it is easy to use with Arduino and other microcontrollers.

What you need

• Arduino or compatible microcontroller I2C
• USB cable
• 3.3V-5V power supply

Steps

1. Connect VCC to the 3.3V-5V of the microcontroller
2. Connect GND to the ground of the microcontroller
3. Connect SDA to the SDA pin of the microcontroller
4. Connect SCL to the SCL pin of the microcontroller
5. Install the Adafruit_Sensor and Adafruit_SHT20 libraries in the Arduino IDE
6. Include the libraries in the code
7. Initialize the sensor in the setup()
8. Read the temperature and humidity values in the loop()

Example code

Adafruit_SHT20 sht20;
void setup() {
  Serial.begin(9600);
  sht20.begin();
}
void loop() {
  float temperature = sht20.readTemperature();
  float humidity = sht20.readHumidity();
  Serial.print("Temp: ");
  Serial.print(temperature);
  Serial.print(" C, Humidity: ");
  Serial.print(humidity);
  Serial.println(" %RH");
}

Mini project

Create an alarm system for the environmental condition. When the temperature or humidity exceeds the set values, send an email or SMS.
