The LSP27HHW also embeds a temperature sensor.
Comparing the datasheet, I can´t find any diference.
Why LPS27HHTW is 1€ more expensive?

Hi @APere.7 ,
the difference between the two part numbers relies on the fact that the LPS27HHTW not only has an embedded temperature sensor, but is also calibrated at production level to guarantee a Temperature accuracy in the ±1.5 °C range, as you can see from the datasheet, p.1.
This is the price difference root cause: however, if you have a temperature reference on your system, you can of course calibrate the LPS27HHW embedded temperature sensor (in offset at 25°C and gain versus temperature in the defined range) via software, getting the desired accuracy. This is useful especially in post-solder condition.

Thank you.
I have an other question for this sensor.
The pressure range given in darasheet is 260-1260 hPa. But they can read until 1544 hPa without problems (aparentely).
I coudn´t aprecciate any desviation or error in measure out of spectication.
Could i have any information about the Relative accuracy in the range 1260-1544hPa?
And finally, I would like to congratulate you for this sensor.
I consider it to be the best and most accurate barometric sensor on the market.
