Review: 0-10kPa only - These are 0-10kPa, not 0-40kPa. Either wrong sensor, or hardwired incorrectly. I tried changing the gain via software and it doesn't increase the gain. Either stays 0-10kPa, or outputs an unchanging signal. Works fine if you only want 0-10kPa. Update: While powered, it's possible to measure all the pins on the pressure sensor and find the one in the middle that matches the supply voltage (ie 3.3V). It'll be the middle one on the same side of chip as the GND. If you desolder/disconnect that middle pin, and deliver a lower voltage directly to that sensor's pin, you'll get about 3.3x the pressure range, so closer to 30kPa. You could go lower and get an even wider range. I'll probably keep mine as
