Pressure Plug Display a K-type thermocouple with anThe Pressure Plug is a small board containing the BMP085 barometric pressure and temperature sensor. This tiny sensor communicates directly over I2C. Some processing is required to arrive at properly adjusted readings, this is available by using the BMP085 class in the JeeLib library. An I2C bus running at 3. 3V is used as interconnect, with all the power and signal lines brought out to to both sides of the board to allow daisy chaining with other I2C
