Here is a little interface board for the BMP085 atmospheric pressure sensor – I2C based and daisy-chainable as usual:
This sensor is a bit tricky to solder by hand, as you can see in an older post.
The sensor is extremely sensitive and measures both pressure and temperature. The “bmp085demo” sketch in the Ports library hasn’t changed:
Here’s some sample output:
The temperature is not 27°C around here ;) – this board is simply still cooling down from the reflow!
This new Pressure Plug will replace the hand-soldered one in my OOK relay, of course.
