Interfacing SHT35 Temperature & Humidity Sensor with Arduino

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°

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:
