4.1 I

C Interface and Timing

For integration with a micro-controller, the humidity module has an I

C-compatible interface which supports both

100 kHz and 400 kHz bit rates. The I

C slave address is programmed by default on 0x28 and can be adjusted in the

entire address range (0x00 to 0x7F). Hence, up to 126 humidity modules can be operated on a single I

C-Bus.
