Breakout board to allow multiple (up to 6) one-wire DS18B20 temperature sensors on wire to be easily wired to a single one-wire RJ45 bus for easy connection to the emonPi or other Sheepwalk Electronics boards (e.g DS18B20 Raspberry Pi Board). 

Using the two RJ45 connectors on the board multiple breakout boards can be strung together to add even more sensors! 

If you just want to connect a single DS18B20 Temperature sensor to the emonPi a DS18B20 wired directly onto RJ45 is the easiest option. Multiple DS18B20 on Rj45 can be strung together using RJ45 expander board .

An RJ45 coupler can be used to extend RJ45 sensor cables.
