SHT35 Sensor and Arduino Uno

by arduinoguy71

In this article we look at the SHT35 humidity sensor, this is very similar to the SHT30 and SHT31 sensors in the same family but this is a more expensive one.

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

Name   Link
Arduino Uno
SHT35
Connecting cables

 

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: 27.65°C
Humidity: 58.01%
Temperature: 28.30°C
Humidity: 59.60%
