SHT3x Humidity & Temperature Sensor
The SHT3x sensor is the most accurate and precise sensor for measuring humidity and temperature parameters compared to other temperature sensors like LM35, Thermistor, DS18B20 & DHT11/DHT22. Thus SHT3x can be used for industrial applications because of the high accuracy and good sensitivity. Its Relative Humidity operating range is 0 – 100% and Temperature operating range is -40° to +125°C (-40° to +257°F).

SHT3X Temperature and Humidity sensor, How it works and its pinout diagram:
There are many sensor boards out in the market which can measure temperature and humidity wisely, but when you need an accurate, precise and compact only few of them comes under the list. One of them is SHT3x series sensor as they are successors of SHT2x that set the industry level standards in humidity and temperature measurements, SHT3x comes with SHT30 and base version, SHT31 a standard version and All the way goes to SHT35 High end version which can be used in automotive level sensing.
SHT3x is packed with a completely new CMO Sens Chip, which will increase reliability along with improved accuracy in measuring. The SHT3x offers a range of new features when compared with SHT2x and other sensors, such as enhanced signal processing, two distinctive and user-selectable I2C addresses(0x44 or 0x45), an alert mode with programmable humidity and temperature limits, and communication speeds of up to 1 MHz.
