I’ve just got this to work with the Bus Pirate. Great sensor. One note though about the product description… The absolute accuracy is +/– 1 hPa, not 0.03 hPa. Resolution is down to 0.03 hPa.
Converting the coefficients was the hardest job since the datasheet nor the application note give the conversion formula. It’s only in C-code. And since I’m not that good at C it took a little time to understand how some of the coeffs are negative.
If you are deciding between this and MPL115A2I2C take this. I have both and MPL115A’s coeffs are way harder to convert (fixed point numbers).

This thing is great! I’ve been debugging an I2C pressure sensor for days and with this I finally got it to work.

I’d like the I2C version breakout board too. Any news on that?
