Arduino Barometer Project Using BMP180   Nikodem Bartnik   Arduino Projects Pressure sensors are widely used in drones, weather stations, smartphones and more. It is important to know how this small piece of technology works. We are going to be using the BPM180 sensor. The name of the module is GY-68. The small device can read, pressure, altitude, and temperature. Let’s build a small device that uses BPM180 to read pressure and altitude and uses an I2C LCD display to show that information (You can as well choose to display it on the serial port). Here are the components we need: 1 x Arduino Uno Board 1 x BMP180 pressure sensor 1 x I2C LCD Jumpers wires As usual, we need to do the connection before uploading the sketch into the board. Because both the LCD and the pressure sensor use the I2C, we have to connect the pins SDA and SCL to the analog pins 4 and 5. Some barometers have a Vin pin and some a 3V3 pin. If yours has a Vin, it should be connected to 5V
