Introduction

Python driver for Infineon Digital Barometric Air Pressure Sensor(DPS). This single driver is compatible with all the different versions of S2GO Digital Barometric Air Pressure Sensor from Infineon.

Different versions of DPS-

DPS310 The barometric pressure sensors DPS310 offers excellent pressure noise performance and high stability with temperature. Product
DPS368 DPS368 is a miniaturized digital barometric air pressure sensor with ultra-high precision (±2 cm) and a low current consumption, capable of measuring both pressure and temperature. Due to its robust package, it can withstand 50 m under water for one hour (IPx8). Product
DPS422 The DPS422 is a miniaturized digital barometric air pressure and temperature sensor with high accuracy and low current consumption. Pressure sensing is carried out using a capacitive sensor element, guaranteeing high accuracy over temperature. Product

Dependencies

This driver depends on:

python version 3 and above
SMBus

Please ensure all dependencies are resolved before proceeding further.

Steps for installation

Supported hardware --> Raspberry pi Zero/3/3B+/4B

Update apt


sudo apt update

Enable i2c (Interfacing options menu and then I2C enable). For detailed steps see this article.


sudo raspi-config

Install pip3


sudo apt install python3-pip

Install smbus


pip3 install smbus
sudo apt-get install -y python-smbus i2c-tools

Installing from PyPI

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver from PyPI

For current user:


pip3 install DigitalPressureSensor

To install system-wide (this may be required in some cases):


sudo pip3 install DigitalPressureSensor
