In this module sensor-b we use digital barometer Freescale Semiconductor MPL115A2:
Detail description about this chip you can find here MPL115A2
As you see at scheme Raspberry Pi communicate with MPL115A2 via I2C Bus. I2C address is 0x60.
Final PCB is shown below:
Final SENSOR-B case is shown below:
Now we can test it. Firstly attached to pisensor and then we can scan I2C bus.
The result is that address 0x60 appears, but programming this device is more sophisticated than simple thermometer.
