Extension cable for RHT USB

CC USB-RHT sensor uses I2C bus to transit data. 

USB cable contains I2C to USB converter and sensor is based on I2C module

The following diagram shows the final results:

 

To build an extension cable for CC USB-RHT sensor you need:

  1. Cable with at least 3 wisted pairs. Typical UTP unshielded  Cat5e cable used for Ethernet connection can be used for this purpose. 
  2. Male + female SP1310-4P connectors
