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
Distance between sensor and converter (USB cable) can be extended.
We have tested 10m cables - but we know that in theory, this distance might be longer.
The following diagram shows the final results:
To build an extension cable for CC USB-RHT sensor you need:
- Cable with at least 3 wisted pairs. Typical UTP unshielded Cat5e cable used for Ethernet connection can be used for this purpose.
- Male + female SP1310-4P connectors
