-The Raspberry Pi is connected via its GPIO through a ribbon cable, processes all data from I/O modules and is sending responses. All individual I/Os and communication interfaces are connected to the Raspberry Pi's CPU either directly via GPIO or indirectly via I2C. Raspberry Pi also provides network connectivity and USB ports.+The Raspberry Pi is connected via its GPIO through a ribbon cable, processes all data from I/O modules and is sending responses.

 The **1-Wire bus** is used for passive reading of data from corresponding 1-Wire sensors (humidity sensors, temperature sensors etc.). One bus can receive data from up to 15 sensors with a maximum total length of the bus up to 200 meters (provided a suitable [[https://​www.unipi.technology/​cs/​senzory-c11|1-Wire hub]] is used). The **1-Wire bus** is used for passive reading of data from corresponding 1-Wire sensors (humidity sensors, temperature sensors etc.).
