MLX90614 infrared thermometer
Use MLX90614 adapter board from Paparazzi hardware repository. Solder parts, take care of sensor polarity. The I2C address of the MLX90614 needs to be programmed once before it can be used. Connect it as the only sensor to I2C and flash/run it with the IR_MLX_ONE_TIME CONFIG option set (currently available in the master branch only). See Module/Melexis_MLX90614.

PT1000 temperature sensor
Solder the PT1000 sensor (little blue on the picture) to the two correct pads at the edge of the TEMOD-I2C-R1 board, where the pin plugs are. The pads on both side are not connected through. It has to be soldered to the side not carrying the chip. Remove pin header from TEMOD board. Solder 4pin cable to TEMOD, it will be connected to the Umarim through the multi_i2c board below. Fix with hot glue.
