SHT35 Temperature and Humidity Sensor Features
SHT35 is a digital temperature and humidity sensor. This module uses I2C communication protocol and the 2 SCL and SDA pins are used in order to communicate to this sensor. This sensor is ideal for temperature and humidity sensing.
Temperature measurement range: -40°C to 90°C/ Accuracy ±0.2°C
Humidity measurement range: 0-100% RH/ Accuracy ±1.5% RH
You can download the datasheet of this module here.
SHT35 Temperature and Humidity Sensor Pinout
This sensor has 4 pins:
- VCC: Module power supply –2.4V to 5V
- GND: Ground
- SDA: I2C data
- SCL: I2C clock
You can see pinout of this module in the image below.

Interfacing SHT35 Temperature and Humidity Sensor with Arduino
Step 1: Circuit
The following circuit shows how you should connect Arduino to SHT35 module. Connect wires accordingly.
Step 2: Code
Download the SHT35 sensor library from the link below and then install. (It is the same as SHT31)
Tip
If you need more help with installing a library on Arduino, read this tutorial: How to Install an Arduino Library
Step 3: Code
Upload the following code to your Arduino. This code displays the temperature and humidity read in the serial monitor. You can also use the Serial plotter to draw graphs.

uint32_t start;
uint32_t stop;
SHT31 sht;
void setup()
{
Serial.begin(115200);
Wire.begin();
sht.begin(0x44); //Sensor I2C Address
Wire.setClock(100000);
uint16_t stat = sht.readStatus();
Serial.print(stat, HEX);
Serial.println();
}
void loop()
{
sht.read();
Serial.print("Temperature:");
Serial.print(sht.getTemperature(), 1);
Serial.print("\t");
Serial.print("Humidity:");
Serial.println(sht.getHumidity(), 1);
delay(50);
}
After running the code, you will see the following image in the serial output.
