3wire SPI temperature sensor and relay control boards (suitable for Raspberry Pi)

I've been using this LM95071 temperature sensor breakout for quite a while.

Low-power, high-resolution (13-Bit plus sign) digital temperature sensor with an SPI/MICROWIRE compatible interface. 5-pin SOT-23. From Texas Instruments.
Works just fine with the RPi :)

And here is the relay control board:

Coil is 5V DC. Controlled with digital transistor. All you need is 1 GPIO pin from any MCU.
