Connect the VCC pin on the sensor to the 3.3V pin on the Uno. Then connect the SDA (serial data) and SCL (serial clock) pins on the Uno to the corresponding SDA and SCLpins on the sensor. Be aware that the wire library turns on the internal pull-ups to 5V and the MPL3115A2 requires a maximum voltage of 3.6 volts on the SDA and SCLpins.

Pressure sensor 0-200KPa (29psi). Uses I2C to Communicate. Works with Arduino and RPi well. Uses 3.3V only.

The linked code basically just does analogRead()s, calculates a real world value from the results and sends it over Serial. Thats also what you want to

The MPS20N0040D pressure sensor should be wired to the Arduino board and connected to the tee junction tubing. The manometer should also be 

In the hardware setup, apart from the power supply connections (5V & GND), SCK pin of the HX710B module connected to A0 of Arduino Uno, while the OUT pin to A1.

The Bar30 pressure sensor is a pressure sensor designed to be used underwater at pressures up to 30 bar, or around 300 meters depth in water. Upload your code to the Arduino. Open the Serial Monitor, making sure the Baud rate is set to 9600. That's it! You should see pressure, depth, and temperature data being printed to the Serial Monitor.

Hello guys, welcome back. In this tutorial, we will learn how to work the BMP 180 pressure sensor with Arduino code. This sensor has a very small shape 

Connect board VCC (red wire) to Arduino 5V if you are running a 5V board Arduino (Uno, etc.). If your board is 3V, connect to that instead.

In this tutorial, I'm going to show you how to setup the BMP180 on an Arduino, so you can measure barometric pressure, and altitude from the ground or from sea
