SHT30 Sensor and Arduino Uno

Parts Required

You can connect to the sensor using dupont style jumper wire.

This should work with other Arduino boards – I have tried a Mega and Nano for example

Schematic/Connection

I used 3.3v from the Arduino Uno – 5v should be ok if the module has an onboard regulator. You will need to check.

Code Example

This example uses the library from the following location – https://github.com/Risele/SHT3x

Download the zip file from GitHub and import using the Arduino IDE

#include <SHT3x.h>

SHT3x Sensor;

void setup() 
{
  
  Serial.begin(19200);
  Sensor.Begin();
}

void loop() 
{

  Sensor.UpdateData();
  Serial.print("Temperature: ");
  Serial.print(Sensor.GetTemperature());
  Serial.write("\xC2\xB0"); //The Degree symbol
  Serial.println("C");
  Serial.print("Humidity: ");
  Serial.print(Sensor.GetRelHumidity());
  Serial.println("%");

  delay(500);
}

Serial Monitor Output

Temperature: 25.65°C
Humidity: 56.01%
Temperature: 26.30°C
Humidity: 56.60%
Temperature: 26.86°C
