Hello

I ordered 10 samples of the LPS22HH pressure sensor evaluation board (STEVAL-MKI192V1). Upon receipt, I noticed that each board was packaged in a cardboard box but without an anti-static bag.

I then began taking measurements by varying the pressure inside a test chamber. Out of the 10 samples, only 5 function correctly and measure the expected pressure, while the remaining 5 consistently read only 1 bar.

Could this be due to the high sensitivity of the board and the sensor itself, or could it be a delivery issue? I find this particularly concerning as I ordered from three different distributors and encountered the same issue. This leads me to wonder if the sensor is particularly fragile. Could you provide any insights on this?

 

thanks

Please can you recommand me the best board to test ?
