Digital Pressure Gauge 0 to 10kPa (0 to 1.75 psi) with OLED display
The project presented here is a Digital Pressure Gauge using an OLED display. The measuring range of this unit is 0 to 10kPa (0 to 1.75 psi). Additional this compact open-source hardware is Arduino compatible. This board can be used for measuring low pressure up to 1.75psi with great accuracy. The board contains an MPXV5010DP analog pressure sensor, ATmega328 microcontroller, and 0.96 inch I2C OLED display. The board can also be connected to other high-pressure analog sensors from NXP. The operating power supply is 5V DC and it requires 25mA of current. The output of the pressure sensor is 0.2V to 4.75V that proportional to applied pressure. The analog output of the sensor is connected to the A0 analog pin of the ATmega328 chip. A 4 pin header connector is provided to mount the OLED display. A4, A5, VCC, and GND pins used to interface the display. You can download the sample Arduino code to test the board.
