Simple and lean SHT4X I2C interfacing
No Library, No structures, just one straight forward code example to interface.
You'll need to connect the SDA and SCL pins of the sensor to the corresponding SDA and SCL pins on your microcontroller.
Connect 3.3V and Gnd to power lines, see example of Eval board
I2C Bus Address is 0x44 - default (or 0x45)
