Thermocouple and MCP9600 (i2c)
This page explains how to create and setup the MCP9600 Thermocouple amplifier board and the thermocouple
How to prepare the MCP9600 and thermocouple
The thermocouple needs an amplifier board to work. To prepare the sensor you need to solder the thermocouple to one side of the amplifier board and attach a cable with a connector the other side of the amplifier board.
Cut a 10 cm long piece of the ethernet cable and cut the cable that comes with the MCP9600 sensor in two.
Strip the wires and place a small piece of heat shrink on the connector side of the cable as far away from the solder joint as possible. Solder the wires togheter:
Red -> Red (POWER)
Black -> Black (GND)
Yellow -> Yellow (SCL)
White -> Orange (SDA)
Soldered wires. Let the solder joint cool and pull the heat shrink over the joint. Heat the heatshrink sealing the joint. If you struggle to pull the heatshrink over the joint you can try using some pliers to press the joint flatt.
Wires with heatshrink. Solder off the green terminal from the MCP9600. Then solder the black wire from the thermocouple on the - side and the white wire on + side.

Two heatshrinks on.
The only thing remaining now is to strip the other side of the ethernet cable, and connect it to a male socket.
