>>  SHT21 Humidity Sensor Module is a sensor board based on digital temperature and humidity sensor SHT21. SHT21 is a low-cost, easy to use, highly accurate, digital humidity and temperature sensor. This sensor is ideal for environmental sensing and data logging and perfect for weather stations and humidity control systems. All you need is two lines for I2C communication and you'll have relative humidity readings and very accurate temperature readings as a bonus
  >>   Typical Applications:
           -Homes, basements and HVAC systems for measuring humidity
           -Home ventilation, heating and air conditioning systems
           -Meteorology stations to predict or check weather temperatures
           -Gardens or greenhouses to check humidity and temperatures

https://playground.arduino.cc/Main/sourceblock_1/index.txt?action=sourceblock&num=1// i2c_scanner

//

// Version 1

//    This program (or code that looks like it)

//    can be found in many places.

//    For example on the Arduino.cc forum.

//    The original author is not know.

// Version 2, Juni 2012, Using Arduino 1.0.1

//     Adapted to be as simple as possible by Arduino.cc user Krodal

// Version 3, Feb 26  2013

//    V3 by louarnold

// Version 4, March 3, 2013, Using Arduino 1.0.3

//    by Arduino.cc user Krodal.

//    Changes by louarnold removed.

//    Scanning addresses changed from 0...127 to 1...119,

//    according to the i2c scanner by Nick Gammon

//    https://www.gammon.com.au/forum/?id=10896

// Version 5, March 28, 2013

//    As version 4, but address scans now to 127.

//    A sensor seems to use address 120.

// Version 6, November 27, 2015.

//    Added waiting for the Leonardo serial communication.

// 

//

// This sketch tests the standard 7-bit addresses

// Devices with higher bit address might not be seen properly.
