Pinout
This is a brief description of how to connect this board to a microcontroller, however proper research is still required to avoid damaging the sensor:
VCC – Connect to 3.3 or 5v output pin.
OUT – Connect to a digital Pin.
SCK – Connect to another digital pin on your microcontroller.
GND – Connect pin to Ground on your microcontroller.
Application
It is can be used in your project to detect air pressure and water level.
