A sensor with digital output will only give you information whether the pressure is below or above given threshold. You can connect it to digital input of UniPi. You have to decide whether this is sufficient for your project or not.
After adding "pigpiod" to the "Required-Start" label for evok daemon script … I am still in problem when warm/cold reboot raspberry with UnipiBoard.
So, I have decided to cron an evok service restart after some seconds after a raspberry restart.

Resolved but not fully. The situation now is following. I have two devices connected to DI_2 and D_3. They show the same value as expected as they measure the same power line. Nevertheles DI_1 increasing the value as well even without connected device. Its value is aproximately a half of the DI_2 and DI_3. I made no changes on debounce time. Possibly bug in evok?
