Hi everyone. Just wander if anyone have calibrated this sensor using a manometer? As the chart given in the documentation (http://prntscr.com/8d6wc1) doesn't allow to enter very accurate numbers.

Hi,

Check the datasheet on device; it has a linear response, which means you can define the sensor using a 2 point map.

20KPa = 0.5v ; 250 KPA is 4.75v.

When defining a 2 point map you can set the first two map columns and then fill the rest of the map with the same value as the 2nd column.

Let us know how it goes!
