A Particle library for the Si7021 Temperature and Humidity sensor, based on the Sparkfun Si7021 Breakout, but with support for Particle devices with multiple I2C buses (for instance, the Electron).


Connect A Photon or Electron, add the Si7021_MultiWire library to your project and follow this simple example:

#include "Si7021_MultiWire.h"
Si7021_MultiWire si7021_MultiWire = Si7021_MultiWire(Wire); // Use Wire (Photon) or Wire1 (Photon and Electron)

void setup() {

void loop() {

TODO: Describe Si7021_MultiWire


Here's how you can make changes to this library and eventually contribute those changes back.

To get started, clone the library from GitHub to your local machine.

Change the name of the library in to something different. You can add your name at then end.

Modify the sources in and with the new behavior.

To compile an example, use particle compile examples/usage command in Particle CLI or use our Desktop IDE.

After your changes are done you can upload them with particle library upload or Upload command in the IDE. This will create a private (only visible by you) library that you can use in other projects. Do particle library add Si7021_MultiWire_myname to add the library to a project on your machine or add the Si7021_MultiWire_myname library to a project on the Web IDE or Desktop IDE.

At this point, you can create a GitHub pull request with your changes to the original library.

If you wish to make your library public, use particle library publish or Publish command.
