Preparation

Use of the same sensor on i2c usually limited by 1 or 2 (using ALT i2c address) of the same type. And SHT20, SHT21, SHT25, HTU21 is actually the same type, so to be able to compare measurement there is need to use i2c multiplexer. In the case of 8 line multiplexer, there is a possibility to have 8-16 sensor of the same time to be connected with Arduino.
